The concentrations of the solutions, used in Mohr method (titrimetric method for chloride), were changed and evaluated in the different pathway to obtain new spectrophotomelric method for chlorid analyses. The principle ol the method is based on two reactions. First, all chlorid precipitate with the silver, and second, the rest of the silver react with chromate tons. After centrifugation, the restness of the chromate in the supernatant of the solution is related to the chloride concentration in the test tubes and chloride concentration is calculated via optic density of the rest ot the chromate. Since no chloride added in the reagent blank tube, the differences of the optic density of the chromate in reagent blank and test tubes are related to the chloride concentration directly. In a number observations for the analyses of the K₂CrO₄, it is found that the ideal vawelength is 380 nm.
