Solutions Vocabulary

Chemistry

Mixture

A combination of two or more substances that are not chemically bonded.

Heterogeneous mixture

A mixture where you can see different parts, so not evenly mixed.

Homogeneous mixture

A mixture that looks the same throughout, evenly mixed

Solution

A homogeneous mixture where one substance is dissolved in another.

Solute

The substance that gets dissolved.

Solvent

The substance that does the dissolving.

Dilute

 A solution with a small amount of solute.

Concentrated

A solution with a large amount of solute

Saturated

A solution that can’t dissolve any more solute

Unsaturated

A solution that can still dissolve more solute.

Miscible

Liquids that mix completely together.

Immiscible

 Liquids that do not mix (like oil and water).

Solubility

The ability of a substance to dissolve in another.

Supersaturated

A solution that holds more solute than it normally can.

Factors that affect solubility

1. Temperature – Higher temperatures usually increase solubility.

2. Pressure – Affects gases (higher pressure = more dissolved).

3. Surface area/stirring – Smaller pieces and stirring help dissolve faster.
