acids and bases

neutral solution

numbers of hydrogen ions and hydroxide ions are equal

acidic solution

contains more hydroxide ions that hydrogen ions

basic solution

contains more hydroxide ions than hydrogen ions

acid

a chemical compound that increases the concentration of hydrogen ions in aqueous solution

base

a substance that increases the concentration of hydroxide ions in aqueous solution

strong acid

one that ionizes completely in solution

weak acid

an acid that releases few hydrogen ions in solution

strong base

one that dissociates completely to produce OH

weak base

one that produces few OH

monoprotic acids

an acid that can donate only one hydrogen

polyprotic acids

an acid that can donate two or more hydrogen ions

acid (bronsted)

molecule or ion that is a proton donor

base (bronsted)

molecule or ion that is a proton acceptor

conjugate acid

the species that is formed when a bronstedlowry base accepts a proton

conjugate base

the species that remains after a bronstedlowry acid gives up a proton

amphoteric compound

can act as both an acid and a base

acid (lewis)

an atom, ion, or molecule that accepts an electron pair to form a covalent bond

base (lewis)

an atom, ion, or molecule that donates an electron pair to form a covalent bond
