Question

In N H 3 solution of Z n 2 + , Z n 2 + form Z n N H 3 4 + 2 In this solution, to increase the concentration of Z n 2 + we are to add -, H 2 O, H C l, N H 3, Either H 2 O or H C l

MARKS App · Accepted Answer

Z n a q + 2 + 4 N H 3 ( a q ) ⇌ Z n N H 3 4 a q + 2 In the presence of H C l , N H 3 is removed from the equilibrium, therefore, Z n 2 + concentration increases
