Describes the Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases, and explains the relationship between them. Includes the meaning of the term conjugate as applied to acid-base pairs.
Explains the terms strong and weak as applied to acids. Defines pH, Ka and pKa.
Explains Kw and pKw, and how these terms define the pH of pure water at various temperatures.
Explains the terms strong and weak as applied to bases. Defines Kb and pKb for a weak base.
Describes the way that pH changes during various acid-base titrations.
Explains how simple indicators work, and what determines the choice of indicator for a particular acid-base titration. This page assumes that you know about pH curves.
Explains what a buffer solution is and how simple buffer solutions work.
