PH & POH Flashcards
pH
=-log[H3O+]
The negative of the common logarithm of the hydronium ion concentration.
Weak acids
Acids that are weak against electrolytes.
Strong acid
An acid that ionizes completely in aqueous solution.
Arrhenius acid
A chemical compound that increases the concentration of hydrogen ions, H+, in aqueous solution.
Arrhenius base
A substance that increases the concentration of hydroxide ions, OH-, in aqueous solution.
Oxyacid
An acid that is a compound of hydrogen, oxygen, and a third element, usually a nonmetal.
Binary acid
An acid that contains only two different elements: hydrogen and one of the more electronegative elements.
pOH
=-log[OH-]
The negative of the common logarithm of the hydroxide ion concentration.
Polyprotic acid
An acid that can donate more than one proton per molecule.
Alkaline
A solution in which a base completely dissociates I water to yield aqueous OH- ions.
Brønsted-Lowry base
A molecule or ion that is a proton acceptor.
Brønsted-Lowry acid
Molecule or ion that is a proton donor.
Monoprotic acid
An acid that can donate only one proton (hydrogen ion) per molecule.
Amphoteric
Any species that can react as either an acid or a base.
Salt
An ionic compound composed of a cation from a base and an anion from an acid.
