The article presents the results of chemical synthesis of nickel hydroxosulfate in the con-
centrated solutions of nickel sulfate. We obtained hydroxisulfates of the following
compo-
sition:
Ni(OH)
х

O, where 0,9 ≤ х ≤ 1,5. The quantity of adsorbed and
chemical adsorbed waters was estimated. The formation mechanism of hydroxisulfate in
the concentrated solution of initial salt is offered.
Keywords:
hydroxisulfate nickel, nickel hydroxide, precipitation conditions.
