I'm doing a lab experiment on Nickel dissolution:
NiO + 2HCl + H2O --> NiCl2-2H2O.
This reaction is also in equilibrium with Fe, Co, Mg which react similarily with the chloride.
Even with a large concentration of Nickel and High Temperatures this reaction does not proceeds very quickly. I'm not very familiar with catalysts and was wondering if anyone knew a good catalyst for these acid base reactions.
thanks,
Bob

What is the strength of the hydrochloric acid you are using? If it's not a high molarity, the reaction will proceed slower since there isn't a lot of HCl to react with the nickel. If you use a more concentrated acid, I'm pretty sure it will speed up a bit. ;D

Make sure not to use too high of a concentration, otherwise it won't react at all.
I think HCl stops working close to 12moles per liter (12 M) according to my teacher
