Safety Information
Nickel(II) chloride hexahydrate Usage And Synthesis
  • Chemical PropertiesGreen solid
  • UsesAnhydr salt as absorbent for NH3 in gas masks. Hexahydrate for nickel electroplating; manufacture of nickel catalysts.
  • DefinitionChEBI: A hydrate of nickel chloride containing nickel (in the +2 oxidation state), chloride and water moeities in the ratio 1:2:6.
  • HazardConfirmed carcinogen.
  • Safety ProfileConfirmed human carcinogen. Poison by intraperitoneal and intravenous routes. Experimental reproductive effects. Mutation data reported. Violent reaction with potassium. When heated to decomposition it emits very toxic fumes of Cl-. See also NICKEL COMPOUNDS and CHLORIDES.
  • Purification MethodsIt crystallises from dilute HCl to form the green hexahydrate. At 70o this dehydrates to the tetrahydrate, and at higher temperatures it forms the anhydrous salt. It sublimes in yellow hexagonal scales in a stream of HCl. Store it in a desiccator as it is deliquescent. [Hart & Partington J Chem Soc 104 1943.]
