Otaku Engineer in Great Tang Dynasty

Chapter 2155 The truth is revealed! (middle)

"That's right! The Huansheng San, which can bring dead fish back to life, was indeed made by a poor monk based on the academy's "Chemistry" textbook!"

In the room, Jia'e nodded, and seeing that the teachers and students were still puzzled, he continued: "You may still not understand when you say Huanshengsan, after all, this is just the name given by the poor monk himself, but if you say It has another name, I think you can understand, this Huansheng San is actually sodium peroxide!"

"Sodium peroxide?"

Everyone couldn't help exclaiming, because the name was too familiar to them, Zeng Ziran murmured at this time: "According to the textbook, the reaction between sodium peroxide and water will generate a lot of oxygen, is it because there is a lot of water in it? There is a lot of oxygen, so the dying black fish will suddenly become alive, making people mistakenly think that it has come back to life?"

The teachers and students of the academy who were able to participate in the construction of the telegraph relay station are all strong and solid in engineering. After Zeng Ziran said this, everyone was stunned, and they all turned their attention to Jia'e.

"This little benefactor said it well!"

Jia'e glanced at Zeng Ziran, nodded approvingly, and said:

"In the evening, the black fish used by the poor monk to perform the technique of resurrecting dead fish has been taken out of the water for half an hour before that. You should all know that fish can only use its gills to separate the oxygen in the water when it is in the water, but it cannot It separates the oxygen in the air, so if it is left in the air for a long time, the fish will suffocate and die!

The black fish was stranded for half an hour and was already dying, and the poor monk later installed the fish tank, but the water contained in it was stagnant water, and the oxygen was scarce, so even if the black fish entered the water, it was still difficult to absorb it. Oxygen, in the eyes of outsiders, it is almost a dying fish! .dfyxs.

Gu, you have studied chemistry, and you should all know that 2na2o2+2h2o=4naoh+o2↑, so when the poor monk poured a small amount of Huansheng Powder, that is, sodium peroxide, into the fish tank, the sodium peroxide reacted with the water for a short time. A large amount of oxygen will be generated in the water, and the black fish, which is oxygen-deficient, suddenly gets so much oxygen, and will naturally become alive and kicking! This is also the technique of resurrecting a dead fish in the eyes of the common people~! "wAp.

After listening to Jia'e's detailed explanation, everyone couldn't help but be amazed. Li Tai frowned and asked, "Although sodium peroxide reacts with water, although it will generate oxygen, it will also generate sodium hydroxide in water. Strongly alkaline, won't the fish die if they stay in a strong alkaline solution for a long time?".Κanδhu5.iá

Most of the students nodded secretly, apparently agreeing with Li Tai's question.

Jia Er smiled and said, "Your Highness is a good question! However, the amount of sodium peroxide that the poor monk put into the fish tank at that time was relatively small, and even if sodium hydroxide was formed in the water, its concentration was not high. It will be very high. The water in the whole fish tank is only in a weak alkaline state at most. Such water quality will not cause too much impact on the tenacious black fish. Your Highness, don’t forget some salt lakes. , there are also many fishes, that is to say, for some fish, the alkaline liquid environment will not affect their survival;

Second, due to the urgency of time, before this, the poor monk did not actually experiment with black fish, and he was somewhat unsure, so in the evening, not long after showing the dead fish resurrection to the people, the poor monk People have withdrawn the fish tank because they are worried that the black fish will slowly die due to the alkaline solution environment! His Highness had heard the windows of the guest rooms of the inn, and should have noticed this detail!

However, it was later proved that the poor monk's worries were unnecessary, because until all the people in Jian'an Fang received the fragrance, the black fish in the fish tank was still as lively as before! "
