    Title: Determination of chloride by the Mohr Method Objective: To determine chloride by using Mohr Method. Introduction: The Mohr method is the method used to determine the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added‚ a precipitate of silver chloride forms. Ag+ + Cl-  AgCl(s) (Ksp for AgCl is 1.810-10) The chloride ion (Cl-) is an important anion found in solids and solutions. Chloride is the predominant anion

    that had been used to make the structures. Marble and limestone used to be very common materials for art that was meant to be exposed outdoors. To a surprise‚ the acid rain could turn the calcium carbonate molecules that were found on these stone materials into calcium sulphate molecules. This is the result of calcium sulphate being dissolved by water; acid rain would eventually wash away the outside layer of buildings and statues. There are many examples all across the world of the corrosive effects
