Which of the solutions in Exercise 21 shows the least change in pH upon the addition of acid or base? Explain.
The pH of human blood is steady at a value of approximately 7.4 owing to the following equilibrium reactions: CO2(aq)+H2O(l)H2CO3(aq)H2CO3(aq)+H+(aq) Acids formed during normal cellular respiration react with the HCO3 to form carbonic acid, which is in equilibrium with CO2(aq) and H2O(l).
