Q.1. Addition of ammonium chloride to a solution containing ferric and magnesium ions is essential for selective precipitation of ferric hydroxide by aqueous ammonia. (1985 - ½ Mark)

Ans. T

Sol. True : Function of ammonium chloride is to suppress the ionisation of NH₄OH and thus check the precipitation of Mg(OH)₂ because the solubility product of Mg(OH)₂ is high.
This is used in salt analysis when 3rd group radicals are precipitated. The group reagent are NH₄OH in presence of NH₄Cl.

Q.2. From the acidic solution containing copper (+2) and zinc (+2) ions, copper can be selectively precipitated using sodium sulphide. (1987 - 1 Mark)

Ans. T

Sol. True : K_spof CuS is less than K_sp of ZnS. On passing H₂S in acidic medium, the dissociation of H₂S is suppressed due to common ion effect and it provides [S^2–] which is just sufficient to cross over K_sp of CuS and not K_sp of ZnS. Thus only CuS gets precipitated.
