Question

Which of the followings are correct regarding complexometric titration?

• A. A titration in which colour is changed due to formation of complex
• B. Usually occur when d-block elements are involved
• C. Usually happen when chelating ligands are involved
• D. All of the above

Answer 1

Answer: (D)

All of the above

Complexometric titration: It is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.

It usually occurs when d-block element or chelating legants are involved.
