Blood Buffer - Experiment, Step 5

Step 5



5. When the body senses that the blood pH is low, the body attempts to compensate (increase pH) by increasing the rate of respiration so that more CO2 is expired. This action can be simulated by stirring the solution vigorously. Notice that CO2 bubbles are leaving the solution.



Read pH

Record your observations.

Q13: What is the pH after one minute of vigorous stirring?

Q14: Use equilibrium arguments to describe what happened to the pH?
