Answer:
The correct option is C) Sodium thiosulphate.
Explanation:
- Iodometry, one of the few stable reducing agents when it comes to oxidation of air, is the word used to describe the sort of titration that employs a regular sodium thiosulfate solution like titrant.
- Iodine acts as a mediator in an indirect procedure called iodometry to measure the concentration of oxidising chemicals.
- Thiosulphate ions are quantitatively oxidised to tetrathionate ions in the presence of iodine.
- A substance that is inorganic is sodium thiosulfate.
- Usually, it comes in the form of a colourless or white pentahydrate. The solid is a well-dissolving efflorescent crystalline material.
Sodium thiosulphate is used for the standardisation of iodine.
