So the Ksp for silver chloride is 1.8*10^-10, how could I find the concentration of silver ions in this saturated solution. Then how I find the total ion concentration?
AgCl ==> Ag^+ + Cl^-
Let AgCl solubility is x.
Then (Ag^+) is x and (Cl^-) is x
Ksp = (Ag^+)(Cl^-) = 1.8E-10
Substitute x into the Ksp expression and solve for x. Twice that will be the total ion concentration (neglecting the ionization of water).
