Practice Solvent in Chemistry

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

Quick Recap

The substance that does the dissolving in a solution, 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.
