Answer 1

Answer #1

pH of blood = 7.57

Explanation

We will use the Henderson - Hasselbalch equation for the given problem

pH = 6.1 + log([HCO₃^-] / (0.03) * (pCO₂))

where [HCO₃^-] = 24 mmol/L

pCO₂ = 27.0 mmHg

Substituting the values,

pH = 6.1 + log(24 / (0.03) * (27.0))

pH = 6.1 + log(29.63)

pH = 6.1 + 1.47

pH = 7.57

pH = 7.6

The Henderson-Hasselbalch equation relates the pH of a buffer solution to the pKa of its conjugate acid and the ratio of the concentrations of the conjugate base and acid. The equation is important in laboratory work that makes use of buffered solutions, in industrial processes where pH needs to be controlled, and in medicine, where understanding the Henderson-Hasselbalch equation is critical for the control of blood pH.
