1.	Statement - I: A very dilute acidic solution of Cd^(2+) and Ni^(2+) givesyellowprecipitate of CuS on passing H_(2)S Statement - II : The solubility productof CdS is morethan that of NiS
Answer» Statement - I is true ,Statement - II is also true , Statement - II is the correct explatationfor Statement - I Statement - I is true ,Statement - II is true , Statement - II is the correct explatationfor Statement - I Statement - I is true ,Statement - II is FALSE Statement - I is false ,Statement - II is true Solution :In qualitativeanalysis of basicradicalls cation `CD^(2+)` belongs to GROUP II `Ni^(2+)` Belongsto group IV group II radicals areprecipitate bypasssing`H_(2)S` in acidicsolution .They have low value of solubilityproducts .But that of group IV areprecipitate bypassing `H_(2)S` in alkline solution and have highvalue of solubilityproducts Therefore on passing `H_(2)S` in acidic solution a yellow precipirtate of CuS is formed
