This presentation by Katie Eaton covers the basics of understanding pH and then applies that knowledge to the ocean. She answers questions such as what is pH, how does acidification effect the ocean, and how can we mitigate ocean acidification? This presentation is aimed towards high school students, or introductory chemistry learning levels.
