Web sodium thiosulfate is often standardized with potassium dichromate. Web the principle of standardization of sodium thiosulphate is based on redox iodometric titration with potassium iodate as primary standard. Sodium thiosulphate solution is standardized against potassium dichromate in presence of hydrochloric acid and potassium iodide. Web standardization of 0.1 m sodium thiosulfate solution dissolve 0.200 g of potassium bromate, weighed accurately, in sufficient water to produce 250.0 ml. Potassium dichromate oxidizes the iodide ion in acidic medium to equivalent amount of iodine. Web preparation and standardization of sodium thiosulphate. Dry the primary standard kio3 at 110 °c for 1 hr or confirm that it has already been dried. Web sodium carbonate is added to adjust the ph of the solution to about 9 or 10. Web the amount of standard sodium thiosulfate solution required to titrate the liberated iodine is then equivalent to the amount of oxidizing agent. In the standardization, iodine (triiodide) liberated by potassium dichromate.
