Mixtures: Uniform vs Non-uniform, Colloids, Suspensions, and Solutions

This set covers key concepts from the video about uniform (homogeneous) vs. non-uniform (heterogeneous) mixtures, and the subtypes: colloids and suspensions, plus common examples.

Uniform mixture

A mixture with the same composition throughout; components are not easily seen (also called a homogeneous mixture).

Salt dissolved in water

A solution; a uniform mixture where salt (solute) is dissolved in water (solvent).

Heterogeneous mixture

A mixture with non-uniform composition; components can be seen separately. By example: soil, cement with gravel.

Juice with pulp

An example of a heterogeneous mixture where pulp is visible.

Colloid

A mixture with medium-sized particles that do not settle; appears cloudy and can scatter light.

Suspension

A mixture with large particles that can settle out over time; appears cloudy.

Milk

An example of a suspension (colloid) where fat droplets are dispersed in water.

Soil

A heterogeneous mixture with non-uniform composition.

Cement and gravel

An example of a non-uniform (heterogeneous) mixture.

Soda

A uniform mixture; a solution that looks the same throughout.

Solution

A homogeneous mixture where a solute dissolves in a solvent; looks the same throughout.
