If you were dissolving zinc in HCl and water and the solution is nearing saturation but the acid is still "not used up" will it go super saturated as you keep adding zinc strips? What stops the reaction first, acid depletion or solution saturation? I'm sure there are better acids and metals or reactants to use in this example but zinc came to mind. If the solution is saturated with another metal first, say copper strips to saturation, will it still be possible to dissolve additional zinc? What would happen totwo totally different solutes like sugar into saturated NaCl water solution?
