Question
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
(i) 0.1 M NH3 (ii) 0.1 M AgNO3 (iii) 0.2 M NaBr (iv) pure water
Options
A.(iii) < (ii) < (iv) < (i)
B.(iii) < (ii) < (i) < (iv)
C.(iii) < (ii) = (i) < (iv)
D.(ii) < (iii) < (iv) < (i)
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).
AgBr form complex [Ag (NH3)2]+ in NH3 so solubility is maximum in NH3 (aq).
