The Watts bath for electrodepositing Nickel has undergone a number of changes since the original composition was patented. But fundamentally it still consists of a solution of nickel sulphate. Basically, the reaction involves NiSO4→Ni2++SO42- Ni2++2e-→NiNiCl2 =58.7 Faraday constant, F=96500Cmol-1=26.8AhC-1mol-1
