WebIt should read a pH close to 7. 12. Remove the cap from the end of the pH meter and rinse the probe with 10 mL of distilled water. Turn the pH meter on by. moving the switch at the top to the right. Place the meter in each of the buffer solutions to obtain the pH. Rinse the pH meter with distilled H 2 O between each buffer solution. 13. WebA buffer has a very stable pH. When small amounts of an acid or a base are added to a buffer solution, the pH of the solution changes very little. In many chemical and biochemical systems, buffers are critical. Blood plasma, a natural example in humans, is a bicarbonate buffer that keeps the pH of blood between 7.2 and 7.6.
