Chapter 238 Little Watermelon Hehe!
A smile appeared on Lao Cao's face, "It's not bad. There are more than 10,000 kilograms of milk a year. Let's just say how many mouthfuls of milk have you drank since you settled in Guandong?"

"That's true……"

Sun Jianping took out a bunch of purchased reagents from his pocket and carefully measured the pH value of the water. Oh my god, the alkalinity in the water is frighteningly high!
With this high-concentration alkaline water, even the most powerful bacteria and viruses will be killed, let alone plants!
"Uncle, let's go back and fix the big pot in the brigade later. I told Uncle Yu yesterday to get some dead trees and chop them down for firewood. I'll boil out all the baking soda..."

"Okay, I'll fix it as you say!"

Lao Cao looked at the large puddle of water in front of him, and his heart was pounding!
I didn’t expect that these alkaline water could become treasures!

Whether you can drink milk in the future depends entirely on the contents of this pool!

In the afternoon, he drove the carriage to the team and brought back two large fourteen-seal iron pots. Together with Lao Cao, he used local materials to pick up all the broken bricks scattered around the Tutu Temple. , two stoves were temporarily built.

Lao Cao looked at the patterns printed on the green bricks, sighed repeatedly, and said it was a loss!

"Let's talk to ourselves, but these ghosts and gods cannot conflict with each other. You said that Old Yang was so beautiful and ruined the Earth Temple. He passed away in just a few days. I heard that he is drinking alcohol every day at home...retribution!"

Lao Cao chattered some nonsense, and Sun Jianping listened with a smile while carefully descending into the pit, lifting the alkaline water up with a rice cooker, and pouring it into the cauldron.

There are not only baking soda in the water, but also many other components such as calcium ions and sodium ions. They are now in a water-soluble state. After dehydration, they will be converted into sodium carbonate, calcium carbonate, sodium nitrate and other components.

These things are also treasures!
Find a way to separate them all!
The first thing he thought of was to use the different solubilities of various elements to classify sodium carbonate and sodium chloride, which are easiest to separate, and then sodium nitrate!

This is the most valuable ingredient of all!
but……

What is the chemical equation for separation?

forget!

He looked at the fussy old Cao next to him. Not to mention that he was engaged in chemistry, he didn't even understand what the word "chemistry" meant!

It seems that we can only turn to Miss Qian for help!

"Uncle Cao, help me call Qian Huijun over."

"Yup!"

When Lao Cao saw the little bastard, he was very happy. He didn't say anything, but he had already set his sights on the girl!
Why rush? I'm still waiting to have my grandson!

Seeing Uncle Cao walking with wind, Sun Jianping scratched his head in confusion. I just asked him to call Qian Huijun for me. Why was he so happy?

After a while, Qian Huijun came, his face flushed and his chest rising and falling, which made Sun Jianping swallow his saliva.

B?

There has to be a C!

"What are Captain Sun's orders?" Qian Huijun saw him setting up two more cauldrons. Not knowing what he was trying to do, he blinked and asked narrowly.

"Well, I'll take two questions. They're chemistry questions. How do you separate sodium bicarbonate and sodium nitrate from a pile of alkaline solutions?"

"You can't trouble me with this, just watch!"

Miss Qian picked up a piece of wood and scrawled two strings of chemical equations on the ground. Sun Jianping nodded repeatedly, "Not bad, not bad. After careful consideration by the organization, we have decided to recruit you as a member of the saline-alkali land research team. Are you happy?"

"I'm so happy for you, you big-headed idiot! Did you forget the chemical equations and are too embarrassed to ask others, so you just torment me?" Qian Huijun rolled her eyes at him, then looked around at the large pure white puddle at the bottom, "You This trick is quite effective..."

"That's right!" Sun Jianping curled his lips, "Okay, Comrade Qian Huijun, since you don't want to participate, I won't force you to do anything. Go back and review your barefoot doctor's manual!"

"I'll come if you ask me to come, and leave if you ask me to leave. Wouldn't it be shameful for me to spread the word?" She was no longer in a hurry, picked up a piece of wood and put it under her buttocks and sat down, "I'll see what you do. Purify the alkaline water!”

"Looking down on me?"

What a grumpy little boy I am!

He turned around and squatted down between the two water bowls.

Qian Huijun held her knees with her hands, looked at the large rice field in front of her, and then looked at the Daxinganling Mountains in the distance that were already covered in green, and took a deep breath!

The air here is full of intoxicating sweetness!

that's nice!

Hey, why didn’t idiot Sun say anything?

Uncle Cao...

Uncle Cao is nowhere to be found!
This little old man called me over and ran away!
Miss Qian couldn't suppress her inner curiosity, so she stood up and went behind Sun Jianping. When she saw him constantly stirring the alkaline water in the water pot with a wooden stick, he suddenly heard a loud bang, which frightened him!
"Are you sick!"

Sun Jianping turned around and glanced at her. Qian Huijun raised his eyebrows and squatted down. A faint smell of pancreatic juice penetrated his nose, causing him to rub his nose and move aside, "Did you see that?" , according to the different solubility of each solution, I want to heat the alkaline water next, and then use iron wire to form an iron mesh and put it under it to facilitate the condensation of the components in the solution..."

"That's a good idea!" Qian Huijun nodded!
Idiot Sun is really smart!

"Come help me light the fire!"

"I'm not going to help you light the fire. I have to help Uncle Chen and the others plant their own land..." Qian Huijun stuck out her tongue and disappeared in a flash.

"Jianping, do you like watermelon?"

A long way away, Qian Huijun stopped, put his hands to his mouth, and shouted loudly.

"Nonsense, who doesn't like eating watermelon!"

Sun Jianping smiled, this silly Miss Qian!
"Then I'll plant two watermelons!"

"Okay!"

Watching Miss Qian leave, Sun Jianping squatted down, woven the wire into an iron net, and propped it up in the cauldron. He thought of the word watermelon again and smiled mischievously.

C…

Little watermelon hehe!
It’s so quiet around here!

The wind blew gently across the flat salt-alkali land, and only the melodious chirping of the birds in the distant trees, mixed with the sound of wood burning in the stove, seemed so quiet and peaceful.

He straightened his waist, moved his knees, and his heart became comfortable with this vast world!
The great rivers and mountains of the motherland!

Li Xiuzhi quickly planted three-thirds of her own land and returned home with a basket of soil. When she saw her husband poking out a hole in his small vegetable garden, she shook her head helplessly!
My stupid husband!

Don't just dig holes, plant seeds instead!

I know you are farming, but I don’t know which mouse is crazy and digging holes everywhere!

"came back?"

Cao Chungui straightened up and laughed at his wife. Li Xiuzhi rolled her eyes at him angrily, opened the wooden fence door and entered the vegetable garden. She pinched the seeds that Sun Jianping and the others had brought back from the Harbin Academy of Agricultural Sciences, pitting them one by one.

"What's for lunch?" Cao Chungui didn't understand where his wife's unknown fire came from, so he laughed innocently, and Li Xiuzhi rolled her eyes, "Are you short-sighted?"

"What's wrong? I dug the hole so well, every one is horizontally and vertically..."

He even measured it with his feet, "Look, even our dad can't dig such a good hole!"

"Okay, okay, you can go up to the mountains and dig with the wild boar tomorrow. It will definitely be better than the wild boar!"

"That's true..."

"What is it? I'm a grown man who can't hear nice words. You go into the house and light the fire, and I'll light the seeds. I'll let you do this job... finely!"

Cao Chungui scratched his head, "What do you want to eat at noon?"

"Kill the stupid donkey and stew its meat!"

"Where's the stupid donkey?"

"Go inside and look in the mirror, and you'll find it!"

Seeing her husband rushing into the house happily to get the mirror on the counter, Li Xiuzhi was so worried that she slapped her forehead!
This man is so stupid!
See how I deal with you tonight!
"This kid can't even take care of food when he's working!"

After the meal was ready, Li Xiuzhi put a portion in an enamel rice bowl and asked Xiao Yueyue to deliver it to Sun Jianping.

"Hoho, let's go find my brother!"

The little guy was young and didn't know what to worry about, so he skipped out and ran out.

At this time, Sun Jianping was scraping off the crystals attached to the iron wire and putting them into a water pot. These were the crystallized salts that precipitated after heating.

As for how much sodium nitrate is in it, it needs to be tested.

The viscous liquid left in the pot is sodium bicarbonate with relatively high solubility.

"Brother, it's time to eat!"

The little girl ran over and handed him the still warm enamel rice bowl. She tilted her little head and looked at the iron rice bowl, "Brother, what is that white thing in here?"

"It's crystalline salt."

Sun Jianping sat on the ground, took the rice jar, opened it, my dear, today's lunch turned out to be sorghum rice with rice!
