Sodium thiosulphate
Preparation and standardization of Sodium thiosulphate
BACKGROUND Sodium thiosulphate solution is standardized against potassium dichromate in presence of hydrochloric acid and potassium iodide.

The iodine formed in the reaction oxidizes sodium thiosulphate giving sodium tetrathionate ion and the end point is detected by starch solution. Hence, based … Read more
