What is Sodium Formate?

Sodium formate is one of the simplest organic carboxylates, with a white crystal or powder in appearance and a slight odor of formic acid. Slight deliquescence and hygroscopicity. Sodium formate is harmless to the human body, but irritating to the eyes, respiratory system and skin.

The molecular formula of sodium formate is CHO2Na, the chemical structure is HCOONa, HCOONa·2H2O, the molecular weight is 68.007, and the CAS number is 141-53-7.

Solubility: Sodium formate is easily soluble in about 1.3 parts of water and glycerin, slightly soluble in ethanol and octanol, and insoluble in ether. Its aqueous solution is alkaline.

Stability: Sodium formate decomposes into hydrogen and sodium oxalate when heated, and then sodium carbonate is formed.
