The solubility of Ag2CrO4 (Ksp = 1.2 x 10^-12) is several times greater than that of AgCl (Ksp = 1.82 x 10^-10), so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution. If a student uses 1 mg of K2CrO4 as an indicator for 100 mL of sample solution, what is the concentration (M) of chloride ion in the solution when the red precipitate (Ag2CrO4) starts to form?
