Science Separation

Mixture

A combination of two or more substances that can be separated using physical methods without changing their identities.

Compound

A substance formed when two or more elements chemically combine, which cannot be separated by physical means.

Filtration

A physical method used to separate solid particles from liquids by passing the mixture through a filter.

Evaporation

A physical method used to separate dissolved solids from liquids by heating to vaporize the liquid.

Magnetism

A physical method used to separate magnetic materials from non-magnetic materials.

Electrolysis of Water

A chemical method that decomposes water into hydrogen and oxygen gas through the passage of electricity.

Chemical Methods

Methods that involve chemical reactions to transform substances into different identities, requiring chemical changes.

Light Test

A method used to differentiate between solutions and suspensions based on light scattering; solutions remain clear while suspensions appear cloudy.

Separation by Physical Methods

Techniques that separate substances without changing their identities, retaining their physical and chemical properties.

Separation by Chemical Methods

Techniques that involve chemical reactions and result in the formation of new substances with different identities.
