To conduct this procedure we collected samples from each site and measured pH utilizing a pH testing kit. Data was recorded and analyzed.
Procedure: 1) Fill two tubes to the first line (5 mL) with sample. 2) Put one tube into the left opening of the color comparator box. 3) Add 6 drops of wide range pH indicator solution to the second tube. 4) Swirl to mix. 5) Put the second tube into the color comparator box. 6) Hold the color comparator box in front of a light source. Turn the color disc to find the color match. 7) Read the result in pH units in the scale window. |
