The best explanation for the dissolution of ZnS in dilute HCl is that: The sulfide-ion concentration is decreased by oxidation to sulfur. The zinc ion is amphoteric. The sulfide-ion concentration is decreased by the formation of H_(2)S. The zinc-ion concentration is decreased by the formation of a chloride complex. The solubility product of ZnCl_(2) is less than that of ZnS .
