Sodium formate; The Formic acid sodium salt is also known as sodium formate, which contains two crystalline water, so it is also known as sodium dihydrate, sodium dihydrate, and Sodiumformatehydrate. Sodium formate is one of the simplest organic carboxylic acids, which are white crystals or powders. It is slightly damp and hygroscopic. Soluble in about 1.3 water and glycerin, slightly soluble in ethanol, octanol, insoluble in ether. Its aqueous solution is alkaline. Sodium formate is decomposed into hydrogen and sodium oxalate when heated, and then produces sodium carbonate.

In leather industry, used as the camouflage acid in chromium leather, used as catalyst and stabilizer, printing and dyeing industry reducing agent. Sodium formate is harmless to the human body and has a stimulating effect on the eyes, respiratory system and skin. Molecular formula is CHO2Na chemical structure is HCOONa, HCOONa· 2H2O.
