Question

B.4.
Arrange the following in the increasing order of their solubility in water.
(a) AgCl, ArBr, Agl, AgF
(b) BeF2, BeCl2, BeBr2, Belz
(c) PbF2, PbCl2, PbBr2, Pbl2 (d) Na2SO4, MgSO4, Al2(SO4)3
(e) LICI, BeCl2, BClz ​

Answer 1

Answer:

Explanation:

size of anion increases, polarisation increases, covalent character increases

and so solubility in water decreases.

(a) AgI < AgBr < AgCl < AgF

(b) BeI2 < BeBr2 < BeCl2 < BeF2

(c) PbI2< PbBr2 <PbCl2 < PbF2

(d) Al2(SO4)3< MgSO4 < Na2SO4

(e) BCl3 < BeCl2 < LiCl
