The Ksp values of MA , MB , MC , MD are `1.8 xx 10^(-10) , 4 xx 10^(-3) , 4 xx 10^(-8) & 6 xx 10^(-5)` respectively . If a 0.01 M solution of MX is added dropwise to a mixture containing A , B , C , D solution the one to be precipitated first will be :

A

`(pH)_(N_BA) lt (pH) _(NaB) `

B

`(pH) _(NaD) lt(pH) _(NaB) `

C

` (pH)_(NaA) lt (pH) _(NaD) `

D

`(pH) _(NaB) =7`

Text Solution

Verified by Experts

The correct Answer is:
A, C
` pH= 7+ ( (pKa+log c)/( 2)) , pH uparrow if pKa uparrow `
