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 CO, is expired. This action can be simulated by stirring the solution vigorously. Notice that CO, bubbles are leaving the solution. Checker by HANNA Record your observations. 7.27 Q13: What is the pH after one minute of vigorous stirring? Q14: Use equilibrium arguments to describe what happened to the pH?

**Experiment Details:**

**Objective:** 
To understand the body's response to low blood pH and the effect of increased respiration rates on CO₂ release.

**Background:**
When the body detects low blood pH, it compensates by increasing the respiration rate, expelling more CO₂. This action can be mimicked by vigorously stirring a solution and observing the CO₂ bubbles leaving the solution.

**Image Explanation:**

- **Diagram/Image:** The image shows a beaker with a solution being stirred vigorously. CO₂ bubbles are visibly rising to the surface, simulating CO₂ release in the body during increased respiration.

- **pH Measurement Device:** The Checker by HANNA device indicates a pH reading of 7.27, suggesting a neutral to slightly basic pH level.

**Instructions:**
- **Record Observations:** Keep track of changes in the solution, particularly the rate of bubble formation and any pH changes.

**Questions:**
- **Q13:** What is the pH after one minute of vigorous stirring?
- **Q14:** Use equilibrium arguments to describe what happened to the pH.

This exercise aims to illustrate the physiological response to pH imbalances and the chemical principles underlying pH adjustments.
