Physical Science Chapter 8 Vocabulary

Supersaturated Solution

A solution that contains more solute than the solvent can normally hold at a given temperature

Unsaturated Solution

A solution in which more solute can be dissolved at a given temperature

Indicator

A substance that changes color in the presence of an acid or a base

molarity

The number of moles of a dissolved solute per liter of solution

Acid

A compound that produces hydronium ions when dissolved; a proton donor

Concentration

The amount of solute dissolved in a certain amount of solvent

Solubility

The maximum amount of solute that normally dissolves in a given amount of solvent at a certain temperature

Base

A compound that produces hydroxide ions when disolved in water; a proton acceptor

Saturated solution

A solution that contains as much solute as the solvent can normally hold at a given temperature

Solvent

A substance in which a solute dissolves

Ionization

The process by which neutral molecules gain or lose electrons

Dispersion

The process of dissolving by breaking into smaller pieces

pH

A measure of the hydronium ion concentration of a solution

Neutralization

A chemical reaction between an acid and a base

Salt

An ionic compound formed when an acid reacts with a base

Dissociation

The separation of ions in an ionic compound as the compound dissolves

Buffer

A solution that is resistant to large changes in pH

Electrolyte

A compound that produces ions when it dissolves
