Blood Buffer - Experiment, Step 8

Step 8



8. When the body senses a high blood pH, it reduces breathing to limit the exhalation of CO2. We can simulate this effect by adding dry ice (solid CO2) to the beaker.



Read pH

Record your observations.

Q18: What is happening to the dry ice?

Q19: Use equilibrium arguments to describe what happened to the pH?
