Water Quality and pH AP1048
An accurate and reproducible pH reading is almost impossible on ultra pure distilled or
deionized water, which you would expect to have a pH of 7. Why? Most pH meters are
unable to give accurate readings when few ions are present. Also, as soon as distilled or
deionized water is exposed to the air, carbon dioxide gas starts to dissolve—thus lowering
the pH of the water and eliminating accurate, repro ducible pH readings.
Did you know that the pH paper you might use would change the pH and give you
false readings? Solution: Use a low ion pH indicator. See page 146 to find this simple kit.

*Note: Resistivity is a measure of how resistant the distilled water is to conducting a current. Impurities, such as ions, cause water to conduct a current better. The fewer impurities present in the water, the more resistant
the water is to conducting a current. Therefore, high resistivity means high water quality. All of the water quality readings listed above are acceptable for the high school science laboratory.
