A) increase the solubility product of III group salts
B) decrease the solubility product of III group salts
C) increase the ionic product of \[O{{H}^{-}}\]and III group radicals
D) decrease the degree of ionisation of group reagent
Correct Answer: D
Solution :
\[N{{H}_{4}}Cl\] is added before \[N{{H}_{4}}OH\], to decrease its ionisation (by common ion effect) so that only IIIrd group radical hydroxides precipitate.You need to login to perform this action.
