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

A

(iii) < (ii) < (iv) < (i)

B

(iii) < (ii) < (i) < (iv)

C

(iii) < (ii) = (i) < (iv)

D

(ii) < (iii) < (iv) < (i)

Answer

(iii) < (ii) < (iv) < (i)

Explanation

Solution

Order of solubility : Complex formation > Pure water > Common ion effect.

AgBr form complex [Ag (NH3)2]+ in NH3 so solubility is maximum in NH3 (aq).
