Is Matter Around Us Pure?

These flashcards cover key concepts related to pure substances, mixtures, solutions, suspensions, colloidal solutions, and their properties.

Pure Substance

A material made up of only one type of particle, having consistent properties throughout.

Mixture

A combination of two or more pure substances that retain their individual properties.

Homogeneous Mixture

A mixture that has a uniform composition and consistency throughout, such as salt dissolved in water.

Heterogeneous Mixture

A mixture with a non-uniform composition where the individual substances can be seen, such as oil and water.

Solution

A homogeneous mixture composed of a solvent and a solute where the solute is dissolved in the solvent.

Suspension

A heterogeneous mixture where solid particles do not dissolve but remain suspended within a liquid.

Colloidal Solution

A heterogeneous mixture where small particles are evenly dispersed throughout a liquid but do not settle out, allowing light scattering.

Solvent

The component of a solution that dissolves the solute, typically present in the greater amount.

Solute

The substance that is dissolved in a solution, usually present in lesser quantity.

Tyndall Effect

The scattering of light by colloidal particles, making the path of light visible.
