True : K base sp of CuS is less than K base sp of ZnS. On passing H base 2S in acidic medium, the dissociation of H base 2S is suppressed due to common ion effect and it provides [S^2-] which is just suffi-cient to cross over K base sp of CuS and not K base sp fo ZnS. Thus only CuS gets precipitated.
