Question

What is a molecular phenomenon where by adding a second solute results in an increase in aqueous solubility of poorly soluble solute?

• A. Peptization
• B. Hydrotrophy
• C. Eutectic mixture formation
• D. Levigation

Hint:

Hydrotropes improve drug solubility without needing emulsifiers or co-solvents—distinct from surfactants.

Answer 1

The Correct Option is B

Hydrotrophy is a solubilization process where a large amount of second solute (hydrotrope) increases the aqueous solubility of another poorly soluble compound without forming micelles, unlike surfactants.
