sodium molybate right answer

Answer 2

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.
