Mixtures

Solutes, solvents and solutions

 

A solvent is a liquid that dissolves a solid, liquid or gaseous solute.  A solute is a substance dissolved in another substance. A solute and a solvent make up a solution. The solute is usually present in a smaller amount than the solvent. 

An example of this would be dissolving a teaspoon of table salt (NaCl) in water (H2O). Water is the solvent and the salt is the solute and together they make a salt (saline) solution. Water is the most comment solvent on earth.
