Step 1
pH is a measure of the acidity or alkalinity of a solution, representing the concentration of hydrogen ions in the solution. It is measured on a scale from 0 to 14, where a pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline. Step 2: Is a Show more…

Which of the following changes in blood pH would you expect to observe in a hyperventilating patient, and what are those changes called? - A drop in pH, acidosis - An increase in pH, alkalosis
Shaiju T.
The normal pH of blood is about 7.4. When the pH shifts above or below that level, the results are acidosis or alkalosis. Review the section on blood pH in Group 14 of the Elements Handbook (Appendix A), and answer the following. a. What chemical species keep $\mathrm{H}_{3} \mathrm{O}^{+}$ in blood at the appropriate $\mathrm{pH}$ ? b. What condition results when there is an excess of $\mathrm{CO}_{2}$ in the blood? c. What is hyperventilation and how does it affect blood pH?
Th pH of blood is steady at a value of approximately 7.4 as a result of the following equilibrium reactions: $$ \mathrm{CO}_{2}(a q)+\mathrm{H}_{2} \mathrm{O}(l) \leftrightharpoons \mathrm{H}_{2} \mathrm{CO}_{3}(a q) \leftrightharpoons \mathrm{HCO}_{3}-(a q)+\mathrm{H}^{+}(a q) $$ The actual buffer system in blood is made up of $\mathrm{H}_{2} \mathrm{CO}_{3}$ and $\mathrm{HCO}_{3}$ - One way the body keeps the pH of blood at 7.4 is by regulating breathing. Under what blood ph conditions will the body increase breathing and under what blood pH conditions will the body decrease breathing? Explain.
