Determination of nickel by potentiometric titration

Tóm tắt

A potentiometric method for the determination of nickel in gold and silver electroplating baths is described. The titration is carried out with KCN. Gold and silver are removed before titration by a reduction process. It is also possible to determine nickel in steel alloys, etc. (see the literature reference).

Ni²⁺ + 4 KCN + 2NH₄⁺ → (NH₄)₂[Ni(CN)₄] + 4 K⁺
