A temperature of - 55Â° C. is obtained by mixing Jo parts of the hexahydrate with 7 parts of snow.
In accordance with his theory of the constitution of salts Werner formulates the hexahydrate as CrC12 (OH2)4 C1.2H20.
It loses four molecules of water of crystallization when heated to 100Â° C. and becomes anhydrous at about 300Â° C. The hexahydrate is dimorphous, a tetragonal form being obtained by crystallization of a solution of the heptahydrate between 20Â° and 30Â° C., and a monoclinic form between 50Â° and 70Â° C. Nickel sulphate combines with many metallic sulphates to form double salts, and also forms addition compounds with ammonia aniline and hydroxylamine.
Driclor contains the active ingredient: 20 % w/w aluminum chloride hexahydrate PH.
Nickel II nitrate hexahydrate, in my very humble opinion, is not one of the stars of the crystal universe.
