Hi Fabbi,

    Nickel sulphamate bath is a high speed plating solution for depositing
Nickel with a wide range of control in its internal stress.  A typical
solution is listed below

Nickel sulphamate               650-780 g/L
Nickel chloride         6-18 g/L
Boric acid                      36-48 g/L
pH                              4.0
Temperature                     60-71 C
Current density         50-800 amp/ft2

(NH)2 SO3 has an oxidation number of -1
Ni has an oxidation number of +2
Together Ni[(NH)2 SO3)]2 has an oxidation number of 0.

I am trying to grow some nickel nanowires... What is this Nickel sulphamate
solution. What is the oxidation number for the Sulphamate ion.  Ni[(NH)2
SO3)]2.

fabbi.
