Acids, Bases, and pH

Mr. Andersen explains the concept of pH, its importance in biology, and how it is determined. He discusses the molecular structure of water, the formation of hydronium and hydroxide ions, and the calculation of pH values. The video covers the characteristics of acids and bases, providing examples like hydrochloric acid and sodium hydroxide. It concludes with the environmental impact of pH changes, such as acid rain and ocean acidification.

Describe how the addition of hydrochloric acid to water affects pH.

What is the significance of the pH scale in relation to acids and bases?

How does acidification of oceans relate to pH levels?
