This question is of interest as we require the correct quantities as we require to start the bath.

That information would be contained in the vendors technical data sheet. If you are not using a proprietary formulation then you need to experiment yourself.

HELLO SIR,
Generally alkaline zinc baths contains 10-15 percent of nickel and rest is zinc.

For good corrosion resistance, the higher the nickel content up to 15%, the better. However if a post treatment such as a chromate, Hex or try chrome, is required 9 percent nickel is suggested. Higher nickel content makes it difficult to obtain a good resistant finish of the post treatment.

A. Recent advances have made an acid zinc nickel deposit possible. It is more ductile than traditional alkaline processes.
Beware that the acidic version is not as time tested as alkaline.
Be optimistic that chromate reception can be as good as with the alkaline version of Zn/Ni.
