For Ag 2 CO 3 , K sp =6.2× 10 12 . For AgCl , K sp =2.8× 10 10 . Solid Ag 2 CO 3 and solid AgCl are added to a beaker containing Na 2 CO 3 ( aq ) . Under these conditions the [ CO 3 2 ]=1.00M . Calculate the [ Cl ] in solution when equilibrium is established.

Options:

Answer:
A
Solution:


[Ag+] to be calculated from Ksp(Ag2CO3) with lower
Kspbut with greater solubility

Ag + = K sp Ag 2 CO 3 CO 3 2 - = 6 . 2 × 1 0 - 1 2 1

= 2.49 x 10- 6M

Cl - = K sp Ag Cl Ag + = 2 . 8 × 1 0 - 1 0 2 . 4 9 × 1 0 - 6

=  1.12 x 10- 4 M
