A combination of a solvent and a solute.
solution
A mixture whose size of particles are large enough to settle out.
suspensions
A mixture whose size of particles are between those in a suspension and a true solution.
colloids
A solution containing the maximum amount of solute for a given amount of solvent.
saturated
A solution that contains more solute than it can theoretically hold.
supersaturated
The dissolved particles in a solution.
Solute
The dissolving medium in a solution.
Solvent
The measurement of the amount of solute that is dissolved in a given quantity of solvent.
concentrations
The amount of a substance that dissolves in a given quantity of solvent at specific conditions.
Solubility
The concentration of solute in a solution measured in moles of solute per liter of solution.
molarity
The concentration of solute in a solution measured in moles of solute per kilogram of solvent.
molality
A scale expressing the acidity or alkalinity of a solution; 7 is neutral, whereas lower numbers are more acidic and higher numbers are more basic.
pH
A chemical substance that neutralizes bases, dissolves some metals; a corrosive or sour-tasting liquid.
acid
A substance that is slippery to the touch and tastes bitter; classified by numbers larger than 7 on the pH scale.
Base
The process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.
ionization
An object that does not have a positive or negative charge; a liquid that is not exceedingly basic or acidic.
neutral
A process in which molecules separate or split into smaller particles such as atoms.
dissociation
A chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests.
indicator
The ion H3O+; consisting of a water molecule and is present in all aqueous acids.
hydronium ion
Any acid that ionizes completely in solutions.
strong acid
An acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution.
Weak acid
A technique where a solution of known concentration is used to determine the concentration of an unknown solution.
