Calculate the molar solubility of Ag2CrO4 Ksp=1.1x10^-12, including net ionic equations. a)0.045 M K2CrO4 b)0.0085 M KOH
a) 0.045M K2CrO4
                               
At equilibrium 2x (0.045+x)

assuming (0.045+x) = 0.045



Molar solubility = 2 * 2.47 * 10^(-6) = 4.94 * 10^(-6) M
b) Since KOH doesn't have any ion in the common, hence the equation will become
                               
At equilibrium 2x x




Hence the molar solubility of Ag2CrO4 is equal to 6.50 * 10^(-5)
