The solubility of carboxylic acid in water gradually decreases with?

A. Decreases in molecular mass
B. Increases in molecular mass
C. Increases the amount of acid
D. Decreases the amount of water


Correct Answer: B. Increases in molecular mass

Detail about MCQs

As carboxylic acids get larger (i.e., as their molecular mass increases), they tend to have more nonpolar hydrocarbon-like portions in their structure, which can interact favorably with the hydrophobic tails of water molecules. This increased interaction with water molecules leads to greater solubility in water.
