Add 2g of sodium. carbonate dilute with 50ml of purified water and add 3ml of starch solution. Titrate with the iodine solution until a. permanent blue color is produced. Note down the volume of iodine solution consumed during titration. Repeat

Jun 26, 2013 · As the iodine is in excess, the reaction of OCl- goes to completion. Now, we must determine the amount of I2 formed by means of titration (with Na2S2O3, sodium thiosulfate) I2 (aq) + 2S2O3-2 (aq) → 2I- (aq) + S4O6-2 (aq) S2O3 2- (thiosulfate ion) is reducing the iodine (I2) in order to form the polythionate (tetrathionate) ion S4O6 -2.

Iodometric and Iodimetric Titration. This titration involves Iodine and Iodide solutions used as titrants. The use of Iodine or Iodide can be done in two ways: Iodimetry Titration (Direct Method) In this type of titration Iodine solution (I 2) is used for titrations of reducing agents. The following are common reactions involving Iodine.Jun 09, 2020 · How do you make iodine solution for titration? Iodine 0.1 N: Weigh 40 g of potassium iodide (KI) in a 500 mL glass-stoppered flask and dissolve in 100 mL of purified water. Let the solution come to room temperature, add 12.7 g of resublimed iodine (I2), restopper the flask, and swirl the flask until the iodine is completely dissolved.
