Understanding Chemistry

 

ACID-BASE EQUILIBRIA MENU

 

Theories of acids and bases . . .

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.

Strong and weak acids . . .

Explains the terms strong and weak as applied to acids. Defines pH, Ka and pKa.

The ionic product for water . . .

Explains Kw and pKw, and how these terms define the pH of pure water at various temperatures.

Strong and weak bases . . .

Explains the terms strong and weak as applied to bases. Defines Kb and pKb for a weak base.

pH curves . . .

Describes the way that pH changes during various acid-base titrations.

acid-base indicators . . .

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.

Buffer solutions . . .

Explains what a buffer solution is and how simple buffer solutions work.
