What is Ammonium Chloride?

Ammonium Chloride is a systemic and urinary acidifying salt. Ammonium chloride helps maintain pH and exerts a mild diuretic effect. This acid forming salt also exerts an expectorant effect by irritating the mucous membranes and is used for alleviation of cough.

It is a white crystalline solid. It is soluble in water(37%). The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. It is used to make other ammonium compounds, as a soldering flux, as a fertilizer, and for many other uses.

What is ammonium chloride used for

Ammonium chloride is mainly used for dry batteries, storage batteries, ammonium salts, tanning, plating, medicine, photography, electrodes, adhesives, etc. Ammonium chloride is also an available nitrogen chemical fertilizer whose nitrogen content is 24% to 25%. It is a physiological acidic fertilizer and suitable for wheat, rice, corn, rapeseed and other crops. It have the effects of enhancing fiber toughness and tension and improving quality especially for cotton and linen crops. However, due to the nature of ammonium chloride, if the application is not right, it will bring some adverse effects to soil and crops.
