The increasing order of Ag + ion concentration in

I. Saturated solution of AgCl

II. Saturated solution of AgI

III. 1(M) Ag(NH 3 ) 2 + in 0.1 (M) NH 3

IV. 1(M) Ag(CN) 2 – in 0.1 (M) KCN

Given: K sp of AgCl = 10 –10 ;K sp of AgI = 10 –16

K instab of Ag(NH 3 ) 2 + = 10 –8

K instab of Ag(CN) 2 – = 10 –21

I < II < III < IV

IV < III < II < I

IV < II < III < I

IV < II < I < III

Text Solution

Verified by Experts

The correct answer is:

In saturated solution AgCl, [Ag + ] = 10 –5 (M)

In saturated solution AgI ,[Ag + ] = 10 –8 (M)

In the solution containing Ag(NH 3 ) 2 + & NH 3 ,

10 –8 = or [Ag + ] = 10 –6 (M)

In the solution containing Ag(CN) 2 – & KCN

10 –21 = or [Ag + ] = 10 –19 (M)
