pH

pH is a measurement of the acidic or basic quality of water. The pH scale ranges from a value of 0 (very acidic) to 14 (very basic), with 7 being neutral. The pH of natural water is usually between 6.5 and 8.2. Most aquatic organisms are adapted to a specific pH level and may die if the pH of the water changes even slightly.

pH can be affected by industrial waste, agricultural runoff, or drainage from improperly run mining operations.

PH Procedure

  • Fill the test tube (0102) to the 10ml line with the water sample.

  • Add one pH Wide Range TesT2b (6459).

  • Cap and mix by inverting until the tablet has disintegrated. Bits of material may remain in the sample.

  • Compare the color of the sample to the pH color chart. Record the result as pH.
