    Precipitation Titration Mohr Method Experimental The chloride ion (Cl-) is an important anion found in solids and solutions. In this experiment‚ the amount of chloride ion in an unknown sample J (NaCl + KCl mixture) of water using the Mohr method is determined‚ which relies on the solubility differences of two anions and the titration endpoint of a precipitate. The net ionic reaction during the titration is as follows: Ag+ + Cl- → AgCl(s) The Ksp for AgCl is 1.8 x 10-10 and
