Product Details
Sodium formic acid and sodium formic acid hydrate. Sodium formate is one of the simplest organic carboxylates. It is white crystal or powder with a slight smell of formic acid. Slightly deliquescent and hygroscopic. Soluble in about 1.3 parts of water and glycerol, slightly soluble in ethanol and octanol, insoluble in ether. Its aqueous solution is alkaline. When heated, sodium formate is decomposed into hydrogen and sodium oxalate, and then sodium carbonate is generated. Sodium formate is mainly used in the production of insurance powder, oxalic acid and formic acid. In leather industry, it is used as camouflage acid in chrome tanning process, catalyst and stabilizing synthetic agent, and reducing agent in printing and dyeing industry. Sodium formate is harmless to human body and irritates eyes, respiratory system and skin. The molecular formula is cho2na and the chemical structural formula is hcoona and hcoona · 2H2O
[appearance] sodium formate is white crystal or powder with slight formic acid smell.
