determine the molar solubility of AgBr in a solution containing 0.163M NaBr. Ksp(AgBr)=7.7x10^-13.
I am really struggling with this problem can some one please help me?
NaBr -------------> Na+ + Br-
0.163 0.163 0.163
AgBr --------------> Ag+ + Br-
x x 0.163
Ksp = [Ag+][ Br-]
7.7x10^-13. = [Ag+] x 0.163
[Ag+] = 4.723 x10^-12
molar solubility = [Ag+] = 4.723 x10^-12M
