Watch the 8 virtual experiments

After watching the following experiments, you will find chemistry really interesting.

Chemistry is probably the " most interesting" subject in nature's subjects (math, physics, chemistry, and biology). The interesting thing is that we can turn into magicians, manually perform "virtual pans" experiments every time to practice.

However, not everyone is lucky enough to see such experiments. And if you are among them, hopefully the picture below will partly satisfy your wishes.

Here, you will be curious about what is happening in the picture? The solution will be available shortly.

1. Chlorine and soda water

This is considered a rather dangerous reaction.

The white powder in the picture is calcium hydrochlorite (Ca (ClO) ₂ ) - a substance commonly used to remove swimming pools. This substance, when used with a small amount of phosphoric acid, is found in soft drinks that will release a huge amount of chlorine gas in a short time.

This is considered a rather dangerous reaction, because the gas formed may be large enough to cause an explosion. Moreover, chlorine is also a poisonous gas, harmful to health.

2. Xesi (Caesium - Cs) and water

This reaction is relatively strong, may break the test tube if overdose is given .

Xesi is an alkali metal like sodium and potassium, so it reacts very strongly with water that forms Bazo CsOH and hydrogen gas.

This reaction is relatively strong, can even break glass test tubes if overdose should be very careful when done.

3. Copper II sulfate (CuSO ₄ ) and iron (Fe)

This is a typical example of such a reaction.

The result will be the same as in picture: Cu and FeSO ₄ . This is a typical example of such a reaction. Iron ions will be dissolved, while pushing copper ions out of solution, forming a reddish brown precipitate.

4. Soap and milk (catalyzed with food colors)

Change color "virtual pan".

The main ingredient of milk is water, but there are also vitamins, minerals, proteins and fats. In particular, fat and protein are very sensitive if the surrounding solution changes.

And this is where the fun begins.Soap solution has a strange "bipolar" characteristic, in which one end of the molecule can absorb water, and the other is not. Therefore, when released into the solution, one end of the soap dissolves into the water, the other end clings to the fat molecules and proteins, causing the link between them to weaken. Finally, fat molecules will bend, disperse in all directions.

5. Burning mercury Thiocyanate

This is a very dangerous reaction, which can be deadly.

If you break down mercury (II), specifically thiocyanate compound (Hg (SCN) ₂ ) , you will feel like you are "falling" to hell.

When burned, mercury (II) thiocyanate will cause an exothermic reaction to create a blue flame and "brown snakes " grow constantly, dangling in the air.

Note: This is a very dangerous reaction, since mercury is a very toxic substance, which can be deadly.

6. Burning Lithium (Lithium)

Lithium is a corrosive, explosive substance.

Lithium is the lightest metal in the periodic table. Like other alkali metals, Lithium is a corrosive, flammable substance. The lithium burning reaction is considered one of the top reactions in chemistry, due to its beauty.

7. Burning Ammonium Dichromate

The burning process will create a large amount of Nito gas.

Not only is mercury thiocyanate, Ammonium Dichromate (NH ₄ ) ₂ Cr ₂ O ₇ also forms a solid monster when burned. Specifically, the combustion process will produce a large amount of nitrogen gas to be raised, pushing the remaining product into high-level Cr ₂ O ₃ oxide.

8. Burn calcium gluconate

To be like the above experiment, what we need to burn is calcium gluconate C ₁₂ H ₂₂ CaO ₁₄ .

In fact, calcium burning will only form calcium oxide CaO. To be like the above experiment, what we need to burn is calcium gluconate C ₁₂ H ₂₂ CaO ₁₄ .

Similar to the burning of Ammonium Dichromate, this compound produces a large amount of CO ₂ , which pushes the remnant of the combustion process upwards, creating the image of the "hell hell" rising.
