The reaction involves nickel(III) acetate reacting with hydrogen sulfide to give nickel(III) sulfide and acetic acid. The balanced chemical equation for the same is:
`2Ni(CH_3COO)_3 + 3H_2S -> Ni_2S_3 + 6CH_3COOH`
Nickel (III) acetate reacts with a hydrogen sulfide in solution to produce the dark brown precipitate of Dinickel tri sulphide, or simply Nickel (III) sulfide and acetic acid. The balanced chemical equation for the reaction is:
2(CH3CO2)3Ni + 3H2S = Ni2S3 + 6CH3CO2H
Being one of the most insoluble salts of Nickel, conversion to dinickel trisulfide (Ni2S3) constitutes a very useful step in the extraction of the metal from its various ores and soluble salts. Ni2S3 is then roasted in air to give nickel oxide, NiO (+2 state), which, in turn, is reduced with carbon to obtain the metal. Ni2S3 also finds use as a catalyst.
