Water Turbidity #9

Well i guess this isn't really about water turbidity, but it has to do with the project. Today we watched presentations. These presentations were really interesting, one that I thought was really good was pH, by Danielle, Kerstin and Coco. This presentation taught me a lot about something that I knew absolutely nothing about. I learned that pH literally stands for potential of hydrogen. It basically means the acidity of water. pH varies in levels between 0 and 14. 0-6.9 is acid. 7 is neutral and 7.1-14 is alkaline.
