A one page tutorial which teaches the viewer how to predict and write equilibrium expressions and use them to calculate equilibrium concentrations. Discusses Le Chatelier's Principle.

Acting as an overview from the General Chemistry Virtual Textbook, this site explores a range of topics related to equilibrium expressions including concentrations and pressures in equilibrium expressions, unchanging concentrations,...

Explains the use of a reaction table when analyzing chemical equilibrium and presents a virtual experiment where the equilibrium constant of a chemical reaction is determined for different scenarios. Requires Java.

[Free Registration/Login may be required to access all resource tools.] Students write the solubility product constant expressions for nearly insoluble ionic compounds and perform calculations for compounds and solubility.

Explains what chemical equilibrium is and the role of the Law of Mass Action. A Java simulation shows the concentration-time curves of a chemical reaction.

Learn where acids and bases fall on the pH scale and the correlation between hydrogen and hydroxide ions. See many examples of how to calculate the pH of a substance. Also find links to the chemistry textbook and tutorials.
