Can we add HCl in a Watts Nickel Bath
What are the down sides of using HCl in Watt's bath instead of NiCl2?
If pH is the only problem, can a mixture of H2SO4 and HCl be used without NiCl2? Will it be a less expensive bath? please reply. Thanks. KRMKaushik Magiawala

pH IS the problem. pH is a critical variable in running a Watts bath and the addition of hydrochloric acid in any substantial amount will quickly drop you below the allowable pH. That's why it is a good idea to keep some nickel carbonate on hand (for those times when you drop the pH a little too much with an acid add).
Consider nickel chloride to be a "neutralized" form of hydrochloric acid (chlorides required for anode corrosion) and an additional source of nickel as well.
