WebThe chlorine-containing gas is shaken with an aqueous solution of potassium iodide (KI), and the resulting iodine is determined by titration. Chlorine is reduced in alkaline solution by an alkali arsenite (e.g., NaAsO 2 ). Back-titration of excess arsenite is carried out with potassium bromate (KBrO 3 ). WebWater can be oxidized to oxygen or chloride ion oxidized to chlorine molecule. 2H 2 O → O 2 (g) + 4H + + 4e – E° =-1.42 V. 2Cl – → Cl 2 + 2e – E =- 1.36V. Hence, the product of electrolysis of aqueous sodium …
