Preparation and standardisation of 0.05 M Potassium Iodate using Sodium Thiosulphate and Starch solution as indicator.
Potassium Iodate Solution Preparation
- Weigh accurately 10.7 g of potassium iodate, previously dried at 110°C to constant weight, in sufficient water to produce 1000 ml.
- Standardize the solution in the following manner.
Potassium Iodate Solution Standardization
- Dilute 25.0 ml of the solution to 100 ml with water.
- To 20.0 ml of this solution add 2 g of potassium iodide and 10 ml of 1M sulphuric acid.
- Titrate with 0.1 M sodium thiosulphate using 1 ml of starch solution, added towards the end of the titration, as an indicator.
- 1 ml of 0.1 M sodium thiosulphate is equivalent to 0.003566 g of KIO3.
