Q.1. If metal ions of group III are precipitated by NH₄Cl and NH₄OH without prior oxidation by conc. HNO₃ ............. is not completely precipitated. (1984 - 1 Mark)

Ans. Fe³⁺

Sol. Fe³⁺; Without oxidation with HNO₃, the Fe²⁺ ions present would not be converted into Fe³⁺. So Fe(OH)₂ will not be precipitated as its solubility product is higher than that of Fe(OH)₃and as NH₄Cl suppresses the ionisation of NH₄OH, this solubility product is not reached.

Q.2. The formula of the deep red liquid formed on warming dichromate with KCl in concentrated sulphuric acid is ............. . (1993 - 1 Mark)

Ans. CrO₂Cl₂

Sol. Chromyl chloride (CrO₂Cl₂).
