Wrong acid in Ni strike

++++

I have a customer who accidentally added one gallon of conc. sulfuric acid to a 115 gallon nickel strike bath ( approx. 80 oz/gal as nickel chloride, 400 mL/gal HCl ). What should they be concerned with?

Thank you,

I don't have a personal experience with this but I noticed a very low HCl concentration in your customer's bath. It should be around 25% by volume and you just have 400mL/gal. That's only about 10%. I think they should add HCl and make some tests to see the effects.

They can build up the Sulfuric acid on the same way like in a Chromm bath, using BaCO3; and filtering it out.
