Acids, Bases, and pH
Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong acid...

Enzyme Action: Trypsin
We demonstrate denaturing by adding the enzyme trypsin to photographic film. Strips of photographic film are added to trypsin solution at different temperatures to determine the optimum conditions for the enzyme. In the right conditions...
