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 -

Options:

Answer:

Solution:

$Z n_{(a q)}^{+ 2} + 4 N H_{3}_{(a q)} ⇌ {[Z n {(N H_{3})}_{4}]}_{(a q)}^{+ 2}$
In the presence of $H C l, {N H}_{3}$ is removed from the equilibrium, therefore, ${Z n}^{2 +}$ concentration increases
