What is the role of ethanol in the preparation of barium sulphate reagent?
What is the role of ethanol in the preparation of barium sulphate reagent?
Show Hint
Ethanol reduces solubility and ensures fine particle formation by preventing super-saturation during precipitation reactions.
Updated On: Jun 16, 2025
- To provide an acidic medium
- To oxidize barium
- To precipitate barium
- To prevent super-saturation
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In the preparation of barium sulphate reagent, ethanol is added to prevent super-saturation. This helps in forming a fine precipitate by reducing the solubility of the product and thus controlling crystal growth.
