Term
Acid
Definition
A substance that dissolves in water and produces hydrogen ion according to the Arrhenius theory. These are proton donors, according to the Bronsted-Lowry theory
Term
Base
Definition
A substance that dissolves in water and produces hydroxide ions according to the Arrhenius theory. These are proton acceptors, according to the Bronsted-Lowry theory
Term
Buffer
Definition
A solution of a weak acid and its conjugate base or a weak base and its conjugate acid that maintains the pH by neutralizing added acid or base
Term
Conjugate acid-base pair
Definition
An acid and base that differ by one H+.
