polar molecules that have H atoms bonded to O, N, or F

hydrogen bonding

the extent to which a solute dissolve in solvent at a particular temperature

solubility

the process in which solvent molecules surround an ion or a molecules

concentration

commonly used unit for alcohol concentration.

proof

defined as the number of moles of the solute dissolved in one liter of the solution

molarity

does not contain any volume term and is defined as the number of moles of solute dissolved in one kilogram of the solvent

molality

are the reactions between acids and bases

acid-based reactions

occur when a cation combines with an anion to form an insoluble product

precipitation reactions

reactions the involve the transfer of electrons between the reactants

sometimes called the gram equivalent. the ratio of a substance formula weight to its number of equivalent

equivalent weight

refers to ''a portion out of one million''

parts per million

a system of measurements that uses a base unit to which prefixes are added to indicate multiples of ten

metric system
