Description
Colorless crystals or white lumps. Sodium bisulfate is used as an inexpensive substitute for Sulfuric acid in dyeing solutions. It is also used in the manufacture of Paper, Soap, magnesia cements, and acid-based industrial cleaners. Sodium bisulfate acts as a Flux in metallurgy. It can pickle metals, carbonize Wool, and bleach Leather.
Synonyms and Related Terms
sodium acid sulfate; niter cake; sodium hydrogen sulfate; sodium bisulphate (Br.); sodium pyrosulfate
Risks
- Strongly irritating to skin, eyes and lungs.
- Hygroscopic.
- Noncombustible.
- ThermoFisher: SDS
