314923 How do we differentiate between \(\mathrm{Fe}^{3+}\) and \(\mathrm{Cr}^{3+}\) in group III in salt analysis?

314924 Assertion :
For gravimetric estimation, silver ion is precipitated as silver chloride.
Reason :
Silver chloride precipitate is white in colour and can easily be formed.

314925 The values of \(\mathrm{K}_{\mathrm{sp}}\) of two sparingly soluble salts \(\mathrm{Ni}(\mathrm{OH})_{2}\) and \(\mathrm{AgCN}\) are \(2.0 \times 10^{-15}\) and \(6 \times 0^{-17}\) respectively. Which salt is more soluble?

314926 One \(\mathrm{dm}^{3}\) solution containing \(10^{-5}\) moles each of \(\mathrm{Cl}^{-}\)ions and \(\mathrm{CrO}_{4}^{2-}\) ions is treated with \(10^{-4}\) moles of silver nitrate. Which one of the following observations is made?
\[\begin{aligned}& {\left[\mathrm{K}_{\mathrm{sp}} \mathrm{Ag}_{2} \mathrm{CrO}_{4}=4 \times 10^{-12}\right],}
{\left[\mathrm{K}_{\mathrm{sp}} \mathrm{AgCl}=1 \times 10^{-10}\right]}\end{aligned}\]
