The solubility of AgCrO4 is several times greater than that of AgCl, so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution. If a student uses 1mg of K2Cro4 as an indicator of 100 ml sample solution, what is the concentration (M) of chloride ion in the solution when the red precipitate (AgCro4) starts to form?
