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.
