Question

11, On addition of ammonium chloride to a solution of
NH4OH:
(a) dissociation of NH4OH increases
concentration of OH decreases
(C) concentration of OH increases
(d) concentration of both NH, and OH increases​

Answer 1

Answer:

NH4Cl is strong electrolyte, it decomposes completely. While the NH4OH is weak base it does not ionises completely. Thus due to presence of common ion NH4+ in NH4Cl, it supresses the ionisation of weak base NH4OH in order to decrease the OH-concentration so that higher group cations will not get precipitated.
