Anwendungen

Sodium formate is used in analytical chemistry to precipitate noble metals. It is used for tanning leather, for dyeing and printing fabrics. It acts as an electroplating agent, an acidulant in the textile industry, a reducing agent, a mordant, a complexing agent. Further, it is used in photographic fixing baths. In addition, it is used as a buffering agent for strong mineral acids and food additive.

Bemerkungen

Hygroscopic. Incompatible with strong oxidizing agents, strong acids. Moisture sensitive
