Others show their swords, I show my missiles!

In a poorly ventilated space, if oxygen needs to be produced for human breathing due to lack of oxygen, the reaction of hydrogen peroxide and potassium permanganate can indeed be used as a potential method for producing oxygen.

However, this approach requires careful consideration of multiple factors in practical applications.

First, from the perspective of chemical reactions, hydrogen peroxide and potassium permanganate can react under appropriate conditions to produce oxygen.

This reaction is one of the common methods for producing oxygen under laboratory conditions.

However, in practical applications, attention should be paid to the control of the reaction and the handling of the products.

Secondly, although the oxygen produced by the reaction of hydrogen peroxide and potassium permanganate can theoretically be breathed by humans, the efficiency and purity of oxygen produced by this method may be affected by many factors.

For example, the concentration of the reactants, the reaction conditions, and other byproducts that may be produced during the reaction may affect the amount and purity of oxygen produced.

Therefore, when using this method to produce oxygen, it is necessary to ensure that the reaction conditions are suitable and to perform necessary treatment on the product to remove impurities.

In addition, it is also necessary to consider that hydrogen peroxide and potassium permanganate are both chemicals with certain dangers.

They may cause irritation or injury when in contact with skin, eyes, etc., and may cause serious consequences such as explosion when in high concentrations or when mixed with other substances.

Therefore, although the reaction of hydrogen peroxide and potassium permanganate can produce oxygen, using this method to produce oxygen for human breathing in a poorly ventilated space requires careful consideration.

Dear readers, if you need to produce oxygen in real life, you should give priority to other safer and more efficient methods of producing oxygen, such as using oxygen generators and other equipment.

Don't copy the novel's approach.

In the environment set in this novel, using hydrogen peroxide and potassium permanganate to produce oxygen is a last resort.

In the spare time of the war, the liberated areas have been vigorously popularizing culture and science, making the liberated areas an oasis of knowledge, where the seeds of culture and science take root and grow vigorously.

As the political commissar of a brigade of more than 100,000 people, Zhao Gang naturally has to set an example.

So he set an example by practicing what he preached.

Whenever there were breaks in battle, he would immerse himself in books, exploring the mysteries of science. His thirst for knowledge and his emphasis on science and technology were fully revealed in his words and deeds.

In addition, after being exposed to science, Zhao Gang felt the importance of science and technology, and he became more attentive in his studies.

As time went by, Zhao Gang not only became more adept in the areas of morality, law, and military affairs, but also made great progress in scientific and cultural knowledge.

During this period, he developed a strong interest in chemical experiments, and through self-study and practice, he gradually mastered certain chemical principles and operational skills.

This accumulation played an unexpected role at the critical moment.

If we want to conduct this oxygen production experiment at this time, Zhao Gang is undoubtedly qualified to be the commander-in-chief.

Zhao Gang knew that when hydrogen peroxide reacts with potassium permanganate, the main chemical reaction product is oxygen.

In this reaction process, other gaseous by-products are usually not directly produced.

However, in actual operation, if the reaction conditions are not properly controlled or there are other impurities in the reactants, some unexpected by-products may be produced.

Therefore, there are certain requirements for the purity of the reactants, but Zhao Gang has no idea what the purity is.

The products produced by the Jiefang District itself will naturally not be adulterated, but whether it is hydrogen peroxide or potassium permanganate, the original intention of producing these materials is not to produce oxygen!

Their main use is in environmental and instrument disinfection.

Now, to use another function of them, we must verify their practicality and reliability through experiments.

Another example is potassium nitrate fertilizer, which is produced to supplement potassium and nitrogen for crops, but some people insist on using it as explosives.

If the manufacturer has taken some anti-explosion measures, resulting in it not exploding when used as explosives, can you say that the manufacturer is a black-hearted business?

In the same way, we need to test whether this batch of fertilizer can explode. And now we need to test the production of oxygen.

Under Zhao Gang's command, the soldiers acted quickly, finding various available utensils, such as cups, bowls, plates, etc., and everything was ready.

The air quality monitoring module in the green purification system in the laboratory was activated, accurately recording the initial oxygen content in the test room, providing reliable data support for subsequent experiments.

Just starting the oxygen monitoring module without using high-power filtering and ventilation systems does not consume much electricity.

Zhao Gang carefully measured an appropriate amount of hydrogen peroxide solution with a measuring cylinder. The clear liquid seemed to contain endless energy.

Then he gently opened the reagent bottle containing potassium permanganate, scooped up a few purple-black crystals with a medicine spoon, and slowly sprinkled them into the hydrogen peroxide solution.

Almost at the moment of contact, the solution began to bubble, and a white gas escaped from the solution at a speed visible to the naked eye and dissipated into the air.

Oxygen is colorless, but the whole reaction is exothermic, which means that when oxygen escapes, it carries water vapor with it. Water vapor itself is also colorless, but when it comes into contact with cold air, it turns into small water droplets, which appear white under the light.

Zhao Gang added a little more potassium permanganate, the reaction became more violent, and some black substance splashed out from the mouth of the cup.

The oxygen concentration figures in the GreenNet system are climbing rapidly.

"It worked!" Zhao Gang and the people in the lab were all excited. "Be careful to use less potassium permanganate and decide whether to produce oxygen based on the oxygen concentration."

The success of the experiment gave every soldier a reassurance.

The soldiers no longer worry about their own safety. Under the command of leaders at all levels, they look for safe corners in batches, take the time to rest, recuperate, and prepare to meet the next challenges.

Not long after, another explosion was heard from above. It was the artillery bombardment of the Japanese ground forces.

The digging army returned to the construction site and continued digging.

Without interference, the excavation progressed quickly. In just one hour, they had dug to a place about 400 meters away from our army's position.

The conscienceless cannon was set up, half buried in the ground, with the muzzle pointing towards the sky above our army's position.

A large number of round cake-shaped explosive packs were transported to the conscienceless artillery positions.

The Japanese regiment commander hid in the command post 600 meters away and issued a cold and ruthless order over the phone: "Die, die, artillery, fire!"

Following this order, the Yellow Shoe Army soldiers tremblingly lit the fuse, and in an instant, the entire battlefield was engulfed by the flames and smoke of the explosion.

Bang, bang, bang... a series of deafening explosions came one after another. The round cake-shaped explosive packs were like messengers of death. Most of them flew towards our army's positions and completely crushed the concrete blocks remaining on the surface.

However, a few explosive packs were spinning in the air and accidentally flew towards the Japanese positions. Some even exploded directly on the spot, bringing the terror and chaos of the artillery fire to the enemy themselves.

There was a sudden cry of grief on the Japanese position, with countless casualties.

This "Death Cannon" is indeed worthy of its name. No matter whether it is the enemy or our own, once it touches it, there is no escape of death.

Even though there were continuous explosions above their heads, our soldiers simply turned over calmly and continued to sink into a deep sleep.

There was no panic or anxiety on their faces; instead, they were full of confidence and composure about the upcoming battle.

This is not only confidence in one's own strength, but also unconditional trust in the indestructible fortifications.

Some of the shallow underground fortifications located beneath the surface had long been turned into the dust of history in the two devastating bombings by the Russian Manrek bombers, becoming a faint, imperceptible trace on the battlefield.

The fortifications that survived were the essence of the entire defense system. Buried deep underground, they withstood the harshest tests and became the most solid shelters for the soldiers.

These fortifications were designed and built by an artificial intelligence automated system. Their design is exquisite and their structure is extremely solid.

Even the bombs weighing one or two tons dropped by Russian Manrek bombers could not shake it in the slightest.

Faced with the tens of kilograms of explosive packs fired by the unscrupulous artillery of the Japanese, these fortifications were like a solid wall of steel, making all the enemy's efforts seem so pale and powerless.

It is with these solid fortifications as support that the soldiers can focus more on the battle itself on the battlefield without worrying about threats from the rear.

As a result, they sleep more peacefully and more firmly.
