What are the toxic chemical liquids

In our daily lives, if we come into contact with liquids that we are not familiar with, we must pay attention to whether they are toxic and try to avoid them. But what are the toxic chemical liquids? Ammonia is a very common liquid in our daily life. It is a toxic liquid. Sulfuric acid, hydrochloric acid, sodium hydroxide and potassium oxynitride are also toxic. If they accidentally get on the skin, they will be corrosive.

1. What are the toxic chemical liquids?

Nitric acid, sulfuric acid, hydrochloric acid, sodium hydroxide, potassium nitrogen oxide, ammonia water, etc. are all irritating to the skin, are corrosive, and can cause chemical burns. Inhalation of strong acid fumes can irritate the respiratory tract, so be extra careful when using it.

2. What are the toxic gases?

Bromine, chlorine, fluorine, hydrocyanic acid, hydrogen fluoride, hydrogen bromide, hydrogen chloride, sulfur dioxide, hydrogen sulfide, phosgene, ammonia, carbon monoxide, etc. are all asphyxiating irritating gases. When using the above gases or conducting experiments that produce the above gases, they must be carried out in a well-ventilated fume hood and a gas absorption device must be installed to absorb toxic gases and reduce environmental pollution.

3. What are the toxic inorganic chemicals?

1. Cyanide and hydrogen cyanide acid are extremely toxic and can cause poisoning very quickly. If the hydrogen cyanide content in the air reaches 0.03%, it can cause death within minutes.

2. Mercury can evaporate at room temperature and is extremely toxic, which can cause acute or chronic poisoning.

When using, it must be done in a fume hood and pay attention to indoor ventilation. If it is accidentally spilled, use a water pump to collect it as completely as possible.

3. Bromine. Liquid bromine can cause skin burns, and its vapor can irritate mucous membranes and even cause blindness. It must be used in a fume hood. Glass bottles containing bromine must be tightly sealed and placed in a metal pile and properly stored to avoid being knocked over or overturned. If accidentally spilled or broken, cover it with fine sand immediately; if skin burns occur, rinse immediately with dilute ethanol or massage with plenty of glycerin, and then apply boric acid vaseline.

4. Metallic sodium and potassium will burn and explode when in contact with water, so be careful when using them. Sodium and potassium should be stored in kerosene or liquid paraffin, placed in an iron can, covered and placed in a dry place. It cannot be weighed on paper, but must be weighed in kerosene or liquid paraffin.

5. Yellow phosphorus is extremely toxic and must not be handled directly with your hands, otherwise it will cause severe and lasting burns.
