15. In a given solution Zn^{2+} is present at the concentrationof 10^{-2}(M). The given solution is saturated H_2S. To obtain the precipitation of ZnS, what should be the minimum pH required in nearest possible integers?Given: In aqueous solution ionic product of H_2S is 10^{-22}and K_{sp} of ZnS 10^{-21}. |
