Practice Solvent in Chemistry

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

The substance in a solution that does the dissolving, typically present in the larger amount.

The 'background' substance that the solute dissolves into. Water is called the 'universal solvent' because it dissolves so many things.

Example 1

easy
Why is water called the 'universal solvent'?

Example 2

medium
Explain 'like dissolves like' using the example of oil and water versus oil and hexane.

Example 3

easy
In a solution of ethanol and water where water is 70\% by volume, which is the solvent?

Example 4

hard
Nail polish does not dissolve in water but dissolves easily in acetone. Explain why a different solvent is needed, and predict whether nail polish would dissolve in vegetable oil.
