Because of its ,high concentration, in most ,wastewater,, chloride is often the most serious source of interference. Its reaction with potassium dichromate follows the equation: 6 C l − + C r 2 O 7 2 − + 14 H + → 3 C l 2 + 2 C r 3 + + 7 H 2 O {\displaystyle \mathrm {6Cl^{-}+Cr_{2}O_{7}^{2-}+14H^{+}\rightarrow 3Cl_{2}+2Cr^{3+}+7H_{2}O} }
