Green Day 3: pH Testing

pH Test. Apparently tap water is neutral/ alkaline.

As a former chemistry minor and present Person Who Is Attracted To Colorful Shiny Objects… I had to go check out this pH display.

pH stands for “potential Hydrogen,” and it’s basically (forgive me, chemists) an approximation of how many hydrogen ions are in a liquid. Lots of hydrogen ions = low pH = acidic; few hydrogen ions = high pH = basic/ alkaline.

This particular company (Pur2o) was trying to sell us on the idea that water should be BASIC, not neutral, and set up this display to prove how acidic most bottled water is, particularly compared to their own very alkaline water. (I’m going to go out on a limb here and guess that they used phenol red as their pH indicator.) Several fairgoers were skeptical about the underlying concept of this.
