These questions require more thought and integrate several concepts.
At normal body temperature, 37 °C, Kw = 2.5 × 10-14.
(a) Calculate the pH of a neutral solution at this temperature.
(b) The pH of blood at this temperature ranges from 7.35 to 7.45. Assuming a pH of 7.40, calculate the H3O+ concentration of the blood at this temperature.
(c) By how much does the H3O+ concentration at this temperature differ from that at 25 °C?
