Front

Dissolve

Back

The mixing of a solid with a liquid to form a solution. Example: Salt dissolves when mixed with water.

Front

Solution

Back

A type of mixture made of one substance dissolved in another. Solutions are transparent because the dissolved particles are so tiny that they do not scatter light.

Front

Colloid

Back

A type of mixture with suspended particles that do not separate on their own. The particles in a colloid scatter light, making the mixture cloudy instead of transparent.

Front

Suspension

Back

A type of mixture with suspended particles that settle and separate over time. Motion is required to keep the components of a suspension mixed together.

Front

Sediment

Back

Solid particles that have settled out of a suspension. Sediment settles when there is not enough motion to keep the particles held up.

Front

Soluble

Back

Able to be dissolved. Example: Sugar is soluble in water.

Front
