Yipin County Magistrate: Start with invincibility

Chapter 109 Secret Weapon
Carbon dioxide is not difficult to produce, it can be obtained by burning limestone, but the difficulty is to collect carbon dioxide.

Qin Feng studied for a long time before he came up with such a method, but he didn't expect it to be really successful.

And he made carbon dioxide to make something that can't be bought in Dazhou-baking soda.

After making baking soda, he can also make a "secret weapon" that allows him to win the bet.

But making baking soda requires carbon dioxide and soda ash.

These two things cannot be bought, so Qin Feng can only start from scratch and prepare them all by himself.

Although Qin Feng is only a librarian, he is good at chemistry.

The production of soda ash is impossible to meet the industrial standards in his current situation, but it is not difficult to produce it crudely. In the book, he has also read about a preparation method with few requirements: plant ash soda production method.

"Mr. Wan, don't stop experimenting. When the candle goes out as soon as it is put into the jar, it means that it is full of what I want, so you should immediately seal the jar for me. Do you understand?"

"Ah? But here... there is obviously nothing!"

Wan Kunming looked at the empty jar, wondering what Qin Feng asked him to seal it up.

"I told you to keep your mouth shut, of course there are things. It's just that not everything in this world can be seen. Just do what I tell you."

Qin Feng's words seemed inscrutable.

Although Wan Kunming didn't understand what it meant, he still obediently kept lighting candles and putting them in the jar, lighting candles and putting them in the jar.

After a while, he exclaimed: "There is indeed something in here. Originally, I had to put the candle at the bottom of the jar to extinguish it, but now, I just need to put it in the middle...Master Qin, what is in it..."

"There is a gas called carbon dioxide in it. If you are interested, I can teach you slowly in the future. This thing cannot be explained in a sentence or two. Now, don't ask."

Qin Feng was busy using various porcelain flasks and beakers, prepared another set of tools, and then went out to bring back the hay that had been drying for a day and a half, and started to burn soda ash.

He first set fire to the hay to get plant ash, then put the plant ash into a bag and washed it, and collected the washed liquid, which contained soda ash and potassium carbonate.

Then, he poured the liquid into the prepared container, started to heat it, stirred it constantly with a porcelain rod, and went through a series of processes to finally get some white powder.

Those powders are soda ash.

"Is the jar full?"

After Qin Feng got the soda ash, he immediately asked Wan Kunming beside him.

Wan Kunming just sealed the mouth of the jar, and responded: "It's sealed, this jar is full of that... er... itch carbon."

"It's carbon dioxide."

Qin Feng couldn't help laughing, corrected a sentence casually, collected all the soda ash, and said to Wan Kunming: "Go, move the jar to the table over there."

There is only one round table, one square table, and one desk in Qin Feng's room, and they are all fully occupied now.

Qin Feng put the soda ash into the container he had prepared earlier, and poured water on it.

He also asked Wan Kunming to turn the jar upside down and set it up high, then took the porcelain tube, carefully pierced the paper seal and inserted it into the jar, and then inserted the other end into the soda ash solution.

"Hold the jar well, hold it safe!"

Qin Feng ordered.

Wan Kunming nodded.

Qin Feng immediately pressed the bottom of the altar-shaped container with his hand.

This jar container was specially designed by him, and the bottom is movable.

With such a press, the carbon dioxide in the jar was pressed into the porcelain jar and blown into the soda ash solution.

Wan Kunming looked at the unchanged liquid with a dazed expression, but after Qin Feng finished it, he said, "It should be done."

A chemical reaction occurs when soda ash solution is blown into excess carbon dioxide.As long as the reflected solutions are distilled, baking soda can be obtained.

The two have been busy until late at night, and finally reached the most critical step.

Qin Feng poured a bag of baking soda into the water, and added a lot of sugar.

"Where are the green oranges?"

"Ah, I have already bought oranges, but they are all unripe, so I can't eat them."

Wan Kunming replied.

"If you don't eat it, what you want is the unripe ones. Quickly fetch those oranges, then slice them into thin slices with a knife, and throw them in here. Hurry up..."

"Yes……"

Hearing Qin Feng's urging, Wan Kunming rushed out like the wind, and soon came back with a basket of freshly cut orange slices, and threw them into the container in front of Qin Feng.

Qin Feng closed the lid, called Wan Kunming, and carried the bucket full to the cellar, where he put it among the ice cubes he bought the day before yesterday.

After finishing all this, Qin Feng clapped his hands and smiled: "Hahaha... that's the end of the job, and tomorrow morning, we will take this and go to Chunxiang Building!"

"This is……"

"It's called soda!"

This is his secret weapon to win the bet with Su Jin!
