A small candle with a faint flame was carefully placed in the flask.

Almost at the same time, the candle burned violently. The candle wicks crackled, and bright light was scattered through the transparent glass.

One person was surprised, "Oxygen!"

One person was excited, "Oxygen!!"

One person is steady, "Don't worry, you have to prove it."

The gas collected by the same receiving device is loaded into a new flask.

The slender medicine spoon threw the black iron powder into it, and after a teasing of fire, it even burned.

"oxygen!"

"oxygen!"

“…”

Another flask that collected gas was thrown in with the charcoal of Mars, and in an instant, it turned into a ball of flame.

The cork was plugged in, and the charcoal was burned quickly. The clear lime water was poured into the flask, and a little shook it. The transparent bottle wall immediately turned into a turbid milky white.

One hand raised the turbid flask high, "This is oxygen!"

Sitting and standing, in the hall with about a hundred people, no one denied this conclusion.

Charcoal gas - charcoal, charcoal, oil, paper, wood, as long as it is a carbon-containing material, the gas that will be produced after combustion - through clear lime water, lime will be generated. This is a fact that everyone knows about the members of the Natural Society.

The preacher, who is also the presenter of the experiment, used three experiments to clearly prove that the gas collected from the experimental device was determined to be oxygen.

The old man sitting in the front stood up first and applauded, and then led all the participants in the entire hall to get up one after another.

Hydrogen combustion produces water, which was confirmed very early, and many people present have done this experiment.

But in turn, no one has been able to succeed by decomposing water into oxygen and hydrogen.

Until today, a scholar, holding the test device he designed, made a proof to everyone present.

Use batteries - electricity, a sub-topic in the forefront of research, to energize water, and then collect the generated gas through special glass tubes.

One of the electrodes produces oxygen and the other produces hydrogen. Before the oxygen experiment, the preacher also used three experiments to prove that it was hydrogen.

Decomposition of water and proving the non-integrative nature of water is one of more than twenty unanswered questions that the Natural Society has solicited public proof.

Now, someone finally proves through a battery that water is not a single element, but a combination of oxygen and hydrogen. The combination ratio is one to two, that is, one part of oxygen and two parts of hydrogen, which can produce one part of water. Therefore, the molecular formula of the water molecule can be determined.

This experiment directly overturned the ancients' arguments and was enough to glorify their lives.

The preacher who has been doing experiments calmly can't help but feel excited at this time, and tears appear in the corners of his eyes

Amid applause, the old man in the front row walked up to the podium and came to the preacher, and the whole audience was quiet.

That old man was the head of the ministers of the Song Dynasty, Su Song, who was the important affairs of the country and Pingzhang.

Walking to the preacher who was so excited that he couldn't speak, Su Song patted him on the shoulder, then turned around and faced everyone.

“Eleventh year ago, we discovered hydrogen.”

Su Song's voice was full of energy.

“Eight years ago, we confirmed that hydrogen combustion produces water.”

Everyone here nodded, and many of them made experiments with their own hands to subvert the views of those around them.

"Three years ago, we confirmed through experiments that hydrogen and oxygen burning only produces water, and confirmed that hydrogen is a component of water."

Yes, many members have understood why the conclusions must be rigorous in this experiment.

This experiment is an extension of the previous experiment, but the previous experiment cannot replace this experiment.

"And today!... The new experiment designed by Xia Xingyan from Chenliu proves from the opposite direction that water is composed of hydrogen and oxygen, and it can be confirmed that this ratio is two to one!"

Once again, applause rang out loud, for Su Song’s speech, for Xia Xingyan’s discovery, and for this breakthrough experiment.

After coming out of the shaded room, the sun was scorching above my head, but no one cared about this little thing at all.

All members who have heard of this report are discussing the just-concluded preaching.

Especially the new experimental methods have attracted everyone's attention.

Water can be electrolyzed, but what about other liquids? Oil, alcohol, vinegar, brine, or sulfuric acid, nitric acid, and will definitely make more interesting discoveries.

The batteries used in this experiment use the initial structure. If better batteries can be made and stronger electricity can be provided, will electrolyzed water produce more interesting results?

Zhang Hui designed a plan for himself in his mind, which is his area of ​​expertise.

Two years ago, he discovered the galvanic element, separated from copper, confirmed the chemical properties, and used a spectrometer to confirm the spectrum of the new element.

When the chapter saw his name in Nature, he only felt that this was the most glorious moment in his life.

But in the following time, Zhang Ying found that he not only had to study in-depth new elements named after his surname and confirm the compounds, but also communicated with other colleagues through letters and participated in local branch activities, and constantly learned mental papers to ensure that he could keep up with the trend.

But in a busy life, he suddenly found that his research on matter was in a bottleneck and could never see a new result. And electrolysis, a brand new experimental method, may bring him something new.

Zhang Hui pondered until the courtyard where he was staying, and then woke up.

He asked his companion around him, "Li Jiu, do you have something to do in the afternoon?"

"I plan to go and see the exhibition at the West Thirteenth Hall."

Zhang Hui looked through the booklet in his hand and had an impression, "From Hedong Military Hospital?! I heard it's very scary."

Medical officials and medical students from Hedong are well-known among the people. The best surgical department in the world, but they are also the protagonists of the horror story of the living and the dead.

But for the members of the Natural Society of Chapter, they are the main force in the papers of the Nature Medical School. The organs of the human body were dismantled one by one by one by one by one by one by one by one by one by one by one, and then they confirmed their function one by one.

In the past, people only knew that there were internal organs, and there were many speculations about the effects of these internal organs. However, through the efforts of the medical officers of the Hedong Military Hospital, the source has been gradually rectified.

But no matter what, at this conference, the human bone specimens and internal organs were presented, and the chapter was still a little scared.

Li Ying didn't care at all, "Bones grow in his body, but they are separated by a layer of flesh. What's there to be afraid of? Should I go together?" He invited the chapter.

Zhang thought about it and shook his head, "I want to try what the effect of salt water electrolysis can have. There should be an experimental device here. If it really doesn't work, it's time to make it now."

"Okay then." Li Ying didn't say much, and smiled.

There are too many interesting things here and I can't delay time for a moment.

Zhang Hui returned to the room and began to design his own experiment.

I've been staying for two days.

Chapter is so satisfied with the environment here that he cannot be satisfied with it anymore.

Regardless of food, clothing, housing and transportation, the arrangements are better than expected.

More importantly, both front, back, left and right are fellow practitioners who pursue natural truth.

As the saying goes, there are great scholars who talk and laugh, but no one can communicate with each other. Zhang Hui can’t talk much with great scholars. When he was in the village, there were not many like-minded companions.

But his neighbors here, his companions, and all the old and new knowledge are devoted to investigating things to achieve knowledge.

Speaking of astronomy, we will not pull the Tai Sui into the Three Walls, and the world will be in chaos. Instead, we will talk about the rings of Saturn, the craters of the moon, the sunspots, and discuss how to better polish the lenses of the telescope.

Speaking of geography, we will not say that the feng shui of the back mountain valley is good and that it can produce noble people, but that the sediment of the Yellow River is deposition, the latitude, and discuss the launch of an expedition to the southern hemisphere.

When it comes to chemistry, no one will make a fuss about the dissolving iron sheets of sulfuric acid, and when it comes to physics, no one will be unable to explain the principle of the rod scale.

To the back of the chapter, this is simply paradise.

After two days in the capital, he didn't think of going to visit the 72 famous stores, see the spring scenery of Fanlou, and see the Zhouqiao.

There is no free time.

Didn't you see it? All the members who came to attend this conference were in exhibition halls, presented meetings, and discussed again and again, throwing the prosperity of Tokyo behind them.

Although when they came to Beijing, they were entrusted various purchasing tasks by their family, family and relatives in the countryside, and many people, after boarding the train, they still thought that they would spend time surfing Tokyo City during the meeting, and now they had no time to think about those things.

Although he was unable to live with several fellow villagers in Yanzhou - Zhang Hui made an appointment with them to set off together and even bought tickets, but because there was something happening at home, he had to postpone it for a few days - but this also made him meet Wei Pu and Li Ying.

Although Li Ying was born in a wealthy family, he did not have the arrogance of the rich children and was in a similar mood to Zhang Hui. Wei Pu was an old friend of Privy Councilor Shen Kuo. Although he was still white, he could speak in front of Ping Zhang.

Li Ying is good at mathematics, so he has also asked Wei Pu for advice in the past two days. Although he has no desire to stick to it, Zhang Hui is also excited to be able to meet Su Pingzhang, Han Xianggong, and Shen Shumi through Wei Pu, whom he admires.

However...Zhang Hui suddenly discovered.

Among the three prime ministers and four ministers in the association's affairs, only Prime Minister Han Gang has not been here yet.

I heard that he was busy with the preparations for the Grand Parliament, and I don’t know when he would be able to make room for it.

However, as the prime minister who deals with the major affairs of the world, it is natural to be busy.

………………………………………

"Yukun, aren't you busy?"

Han Gang was closing his eyes to rest when he heard Zhang Dun's voice, he had to open his eyes.

"Brother Zihou, don't know what?"

"There is something Lu Jifu, I wonder if you have heard of Yukun?"

"What's up?"
