Web[Ag + ] [Cl -] = Kc x [AgCl] This equation suggests that the product of the equilibrium concentrations of the Ag + and Cl - ions in this solution is equal to a constant. Since this constant is proportional to the solubility of the salt, it is called the solubility product equilibrium constant for the reaction, or Ksp. Ksp = [Ag + ] [Cl -] The precipitation of the strongly coloured silver chromate is used to indicate the endpoint in the titration of chloride with silver nitrate in the Mohr method of argentometry. The reactivity of the chromate anion with silver is lower than with halides (e.g. chlorides) so that in a mixture of both ions, only silver chloride precipitate will fo…
