Intro To Solutions

Solution

Composed of at least one solute and one solvent

Solvent

The substance in which a solute is dissolved in

Solute

A substance that is dissolved in a solvent (to form a solution)

Aqueous Solution

A solution in which the solvent is water

Alloy

A solution composed of metals

Miscible

Liquids that dissolve readily in each other in any proportion.

Immiscible

Liquids that do not dissolve readily in each other.

Solubility

The amount of solute that dissolves in a given quantity of solvent at a certain temperature.

Saturated Solution

When no more solute will dissolve in a solution and excess solute is present.

Unsaturated Solution

A solution which is not yet saturated; is able to dissolve more solute.

Precipitate

A solid formed from a reaction

High Solubility

The maximum solubility is greater than or equal to 0.1 mol/L (at SATP)

Low Solubility

The maximum solubility is less than 0.1 mol/L (at SATP)

Factors that affect rate of dissolving

- Temperature
- Agitation
- Particle size

Soluble

Solubility is greater than 1 g per 100 mL of solvent.

Insoluble

Solubility is less than 0.1 g per 100 mL of solvent.
