What are the contraindications to the storage of hydrochloric acid

　　Hydrochloric acid is an aqueous solution of hydrogen chloride, which is acidic and reducible and easy to evaporate. Hydrochloric acid has a wide range of uses: it is an industrially produced substrate material that can be used as a chemical analysis reagent, as a Ph regulator, and can be used to treat stomach acid deficiency. However, it is worth noting that hydrochloric acid is classified as a risk chemical, and the concentration of hydrochloric acid at a concentration of 10% to 25% is irritating to the human skin, respiratory system, etc. Hydrochloric acid with a concentration greater than 25% is corrosive. Therefore, what are the taboos of hydrochloric acid storage? Now let's take a look at it with Guangdong Qikang Chemical!

　　First, hydrochloric acid is easy to evaporate and should be kept tightly sealed. Assuming that hydrochloric acid leaks, hydrogen chloride will evaporate into the air, forming a higher concentration of hydrochloric acid aqueous solution with the water in the air, which corrodes the eyes and skin of the human body. Long-term direct contact with hydrochloric acid in the air can lead to rhinitis, tracheitis and other diseases. Not only is it harmful to human health, but evaporated hydrochloric acid can also corrode surrounding metal objects, resulting in instrument damage.

　　Second, the temperature of hydrochloric acid storage shall not be higher than thirty degrees Celsius, and the humidity shall not be higher than 85%.

　　Third, storage areas should be equipped with emergency spillage equipment to significantly reduce casualties and economic losses. The storage personnel of hydrochloric acid are safely practiced to grasp the handling of emergency leakage of the bottom.

　　Fourth, hydrochloric acid is classified as a precursor chemical, and the storage area should be equipped with special personnel to register the use of hydrochloric acid to avoid illegal misappropriation of hydrochloric acid.

　　Fifth, hydrochloric acid is corrosive, so the container where hydrochloric acid is stored should be clearly marked with a corrosive product mark.

　　Sixth, because hydrochloric acid is acidic, it should be avoided to register with alkaline reagents, such as bases and amines. Acid-base neutralizing repercussions will exothermic. And mixed storage will speed up the deterioration of reagents. And hydrochloric acid can not be stored with alkali metals, flammables, cyanide. Hydrochloric acid and alkali metals have chemical reactions to produce flammable and explosive hydrogen. Hydrogen chloride evaporated by hydrochloric acid is exposed to water and exothermic, assuming that it is stored with flammables, there will be a fire hazard. Hydrochloric acid reacts with cyanide to produce highly toxic hydrocyanic acid.

　　What are the taboos of hydrochloric acid storage? I believe that we have a certain understanding of this aspect, hydrochloric acid is corrosive, we must not be easy to touch in life, assuming that an accident occurs, timely adoption of measures or medical treatment, therefore, it is necessary to know some hydrochloric acid storage taboos.
