Solvent

The substance that dissolves the solute, forming a solution.

Aqueous Solution

A solution in which water is the solvent.

Suspension

A mixture in which particles are dispersed throughout a liquid or gas but are not dissolved and may settle over time.

Colloid

A mixture where suspended particles are small enough not to settle out but large enough to scatter light, resulting in a cloudy appearance.

Filtration

A method of separating mixtures that uses a filter to remove solids from liquids or gases.

Decanting

A separation technique where a liquid is poured off from a solid that has settled to the bottom.

Evaporation

A process of separating a solute from a solvent by heating the solution to form vapor, leaving the solute behind.

What is a solution?

A uniform mixture created when one substance (solute) dissolves in another (solvent).

What is solvent extraction?

A technique that separates components of a mixture based on their solubility in a chosen solvent.
