Select all that apply. The molar solubility of AgCl in 6.5 × 10−3 M AgNO3 is 2.5 × 10−8 M. In deriving Ksp from these data, which of the following assumptions is (are) reasonable? Ksp is the same as solubility. The molar solubility of AgCl is the same in 6.5 × 10−8 M AgNO3 as in pure water. Solubility of AgCl is independent of the concentration of AgNO3. [Ag+] does not change significantly upon addition of AgCl to 6.5 ×...
