Answer:

Correct option is

C

Ag

2

CO

3

; K

sp

=6.2×10

−12

(A) For CaCO

3

,S=

Ksp

=

8.7×10

−9

=9.3×10

−5

M

(B) For CuS,S=

Ksp

=

8.5×10

−45

=9.2×10

−23

M

(C) For Ag

2

CO

3

,S=(Ksp/4)

1/3

=(6.2×10

−12

/4)

1/3

=1.15×10

−4

M

(D) For Pb(IO

3

)

2

,S=(Ksp/4)

1/3

=(2.6×10

−13

/4)

1/3

=4×10

−5

M

Hence, Ag

2

CO

3

has the greatest molar solubility in pure water.
