The molar solubility of Ag2CO3 in a 1.0 M Na2CO3 solution is calculated by considering the common ion effect. The presence of CO3^2- from Na2CO3 suppresses the solubility of Ag2CO3. The solubility product expression is Ksp = [Ag+]^2[CO3^2-]. Assuming x is the solubility of Ag2CO3, [Ag+] = 2x and [CO3^2-] = 1.0 M. Solving 8.1 x 10^-12 = (2x)^2(1.0) gives x = 1.4 x 10^-6 M.
