Nickel hydroxide is a reducing hydroxide and can react with some strong oxidants to generate NiO(OH). It has strong alkalinity. It can ionize a large amount of OH- and a small amount of [Ni(OH)6]4- anions in saturated aqueous solution (mass ratio concentration: 5%), and can also dissolve in strong alkali such as NaOH and KOH to form Na4[Ni(OH)6] or K4[Ni(OH)6]. After evaporation, easily hydrolysable salts such as Na4NiO3 can be obtained.
