TermDefinition
Solute a substance whose particles are dissolved in a solution
Solvent the substance in which the solute dissolves
Dissociation the process in which an ionic compound separates into ions as it dissolves
Dispersion breqking into small pieces that spread throughout the water
Ionization the process in which neutral molecules gain or lose electrons
Solubility the maximum amount of a solute that dissolves in a given amount of solvent at a constant temperature
Saturated solution one that contains as much solute as the solvent can hold at a given temperature
Unsaturated a solution that has less than the maximum amount of solute that can be dissolved
A supersaturated solution one that contains more solute than it can normally hold at a given temperature
Concentration of a solution is the amount of solute dissolved in a specified amount of solution
Molarity is the number of moles of a solute dissolved per liter of solution
Acid a compound that produces hydronium ions when dissolved in water
Indicator any substance that changes color in the presence of an acid or base
Base a compound that produces hydroxide ions when dissolved in water
Neutralization the reaction between and acid and a base
Salt the negative ions in an acid combine with the positive ios in a base to produce this ionic compound
pH of a solution is a measure of its hydronium ion concentration
Buffer a solution that is resistant to large changes in pH
Electrolyte a substance that ionizes or dissociates into ions when it dissolves in water
