Today we got our topics for the new project we are doing in Anne's class. My group (Kerstin, Danielle, and I) are going to be researching pH and water quality testing.
Our prompt: Examine why pH matters in water quality testing. Include a disscussion of what contributes to raising or lowering pH values. What is buffering capacity and why does it matter for water quality? If given a preference, would you prefer to have water with slightly elevated pH or lower pH? Explain why.
What I don't really like is that we didn't choose this topic, but since we didn't turn in our requests in time, this is what we get. I guess we will just have to deal with it because there is a lot to learn about pH and water quality.
From my research so far, I found out that pH is the reciprocal of hydrogen ion concentration in gram atoms per liter.

I also found out information on the pH scale, which shows low and high forms of pH, represented by colors. When pH is low, this means that the substance, when added to water, increases the hydrogen ions, forming what is called an acid. When pH is raised, this means that the reduced substance in the water causes the concentration of the hydrogen ions to reduce also, creating a base.
