What are the hazards of concentrated hydrochloric acid to the human body

Hydrochloric acid is an aqueous solution of hydrogen chloride gas with a pungent smell. It is mainly used in industry and medicine. It also has special effects in daily life. It is rarely used in our daily life and is harmful to the human body, especially concentrated hydrochloric acid. We must be careful when in contact with it, and we must also recognize the harmfulness to the human body. Let’s take a look at the harm of concentrated hydrochloric acid to the human body.

It is very harmful to the skin. But the human body's stomach acid is mainly hydrochloric acid. High concentrations of hydrochloric acid are irritating to the nasal mucosa and conjunctiva, causing corneal opacity, hoarseness, a feeling of suffocation, chest pain, rhinitis, cough, and sometimes blood in the sputum. Hydrochloric acid mist can cause severe pain to the skin of the eyes and face. If an accident occurs, the injured person should be immediately moved to fresh air for oxygen, clean his eyes and nose, and rinse his mouth with 2% soda water. If concentrated hydrochloric acid splashes onto the skin, it should be immediately rinsed with plenty of water for 5 to 10 minutes and soda slurry should be applied to the burned surface. Those with severe conditions will be sent to hospital for treatment.

Pure hydrogen chloride is colorless with a pungent and foul odor. Its aqueous solution is hydrochloric acid. Pure hydrochloric acid is colorless, while industrial products are slightly yellowish due to the presence of impurities such as iron and chlorine. Relative density: 1.187. The melting point of hydrogen chloride is -114.8℃. Boiling point -84.9℃. It is easily soluble in water and is highly corrosive. It can corrode metals and is corrosive to animal and plant fibers and human skin. Concentrated hydrochloric acid emits fumes in the air and forms white clouds when it comes into contact with ammonia vapor. Hydrogen chloride gas is harmful to plants and animals. Hydrochloric acid is an extremely strong inorganic acid. It can react with metals to form metal chlorides and release chlorine; it can react with metal oxides to form salts and water; it can react with alkalis to form salts and water by neutralization; and it can react with salts to form new salts and new acids by double decomposition.

Through the above introduction, we now know the harm of concentrated hydrochloric acid to the human body. Generally, we just need to pay attention to it in normal times. In addition, in life, we often come into contact with this or that dangerous thing or thing. In normal times, we must do a good job of protecting our bodies. This is especially important for our body safety.
