Web10 apr. 2024 · In the reaction, potassium peroxodisulphate and potassium iodide will be used to provide the peroxodisulphate ions and iodide ions respectively. S2O82- (aq) + 2I- (aq) → 2SO42- (aq) + I2 (aq) Sodium thiosulphate is added to react with a certain amount of iodine as it is made. WebThis method starts with a solution of hydrogen peroxideand sulfuric acid. To this a solution containing potassium iodide, sodium thiosulfate, and starchis added. There are two reactions occurring simultaneously in the solution. In the first, slow reaction, iodine is produced: H2O2+ 2 I−+ 2 H+→ I2+ 2 H2O
