Arrange in increasing order of solubility of AgBr in the given solutions.
(i) 0.1 M NH3 (ii) 0.1 M AgNO3 (iii) 0.2 M NaBr (iv) pure water
solubility : Complex formation > Pure water > Common ion effect.
(i) AgBr form complex [Ag(NH3)2]+ in NH3 so solubility is maximum in NH3 (aq).
(ii) AgBr is dissociate into Ag+ and Br– ions in pure water. So solubility increases.
(iii) due to common ion effect in 0.1 M AgNO3 and 0.2 M NaBr solubility of AgBr decreases and higher the concentration of common ion lower will the solubility.
