Question

The estimation of available chlorine in bleaching powder is done by

• A. Acid-base titration
• B. Permanganometric titration
• C. Iodimetric titration
• D. Iodometric titration

Answer 1

The correct option is D Iodometric titration

The estimation of available chlorine in bleaching powder is done by iodometric titration.

Iodometry, also known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point.

Hence option D is correct.
