Explanation / Answer

1)

Ksp of AgCl is 1.6 x 10-10

AgCl...................> Ag+ + Cl-

...............................s M.........s M

Ksp = [Ag+] [Cl-] = 1.6 * 10^-10

s * s = 1.6 * 10^-10

s = 1.26 * 10^-5 M

so molar solubility of AgCl is 1.26 * 10^-5 M.

solubility in g/L solution = 1.26 * 10^-5 * 143.32 = 1.81 * 10^3 g / L.

2)

Ag2CO3 ...............> 2 Ag+ + CO32-

................................2s M...........s M.

Ksp = [Ag+]^2 * [CO32-] = 8.1 * 10^-12

(2s)^2 * s = 8.1 * 10^-12

s = 1.27 * 10^-4 M

so molar solubility of Ag2CO3 is 1.27 * 10^-4 M.

molar solubility of Ag+ = 2 * 1.27 * 10^-4 = 2.54 * 10^-4 M

solubility of Ag2CO3 = 1.27 * 10^-4 * 275.745 = 3.50*10^-2 gm / L
