Question

Which of the following titration methods should be protected from light?

• A. \( \text{Volhard} \)
• B. \( \text{Adsorption} \)
• C. \( \text{Mohr} \)
• D. \( \text{Gay-Lussac} \)

Hint:

Certain titrations require shielding from light to prevent reagent degradation and ensure accuracy.

Answer 1

The Correct Option is D

The Gay-Lussac titration method involves light-sensitive reagents, requiring protection from light exposure. Prolonged light exposure can lead to decomposition or photo-induced side reactions, affecting titration accuracy. Proper storage conditions ensure reliable analytical results.
