Learn about weak acid and base ionization reactions and the related equilibrium constants, Ka and Kb. Relate Ka and Kb to pH, and calculate percent dissociation.

Through a variety of activities, students learn that not all acid and base reactions go to completion, and instead, they establish equilibrium. Acid-base equilibrium expressions have their own constants, ka and kb. Students will perform...

This site from the Rensselaer Polytechnic Institute provides an introduction to chemical equilibrium, covering equilibrium expressions, the pH scale, and presenting how to plot log concentration diagrams.

Learn about what happens when a weak acid is added to water. View examples, an acid dissociation constant table, and a study sheet.

A collection of video lectures from a general chemistry course taught at the University of California, Berkeley. The course teaches periodic table, chemical bonds, molecular shape, phase changes, chemical reactions, stoichiometry,...
