The best explanation for the dissolution of ZnS in dilute HCl is that: A)The zinc ion is amphoteric. B)The sulfide-ion concentration is decreased by the formation of H₂S. C)the sulfide-ion concentration is decreased by oxidation to sulfur. D)the zinc-ion concentration is decreased by the formation of a chloro complex. E)The solubility product of ZnCl₂ is less than that of ZnS.
