The molar solubility of AgCl in 6.5 x 10^-3 M AgNO3 is 2.5 x 10^-8 M. In deriving Ksp from these data, which of the following assumptions are reasonable? A) Ksp is the same as solubility. B) Ksp of AgCl is the same in 6.5 x 10^-3 M AgNO3 as in pure water. C) Solubility of AgCl is independent of the concentration of AgNO3. D) [Ag+] in solution does not change significantly upon the addition of AgCl to 6.5 x 10^-3 M AgNO3. E) [Ag+] in solution after the addition of AgCl to 6.5 x 10^-3 M AgNO3 is the same as it would be in pure water.
