Nickel forms three complexes with hydroxide,NiOH+ (aq) ,Ni(OH) 2 (aq) and Ni(OH (aq) .Which statement(s) regarding the impact of complex formation on the solubility of nickel hydroxide are FALSE?
I Hydroxide behaves as a Lewis acid when forming a complex with nickel.
II The total nickel concentration is [Ni2+]tot = [Ni2+] + [NiOH+] + [Ni(OH) 2] + [Ni(OH].
III As [OH-] increases,the solubility of Ni(OH) 2 initially decreases but then increases.
