Which of these statements does NOT describe pH
A)It equals the logarithm to the base 10 of the reciprocal of the hydrogen ion concentration.
B)It can be calculated if the HCO₃- and CO₂ concentrations in the body fluids are known, even if the H⁺ concentration is unknown.
C)It is lower in arterial blood than in venous blood.
D)The value is higher in an alkaline situation.

Question

Quizplus · Accepted Answer

pH is higher in arterial blood than in venous blood because arterial blood is more oxygenated and carries less carbon dioxide, which forms carbonic acid when dissolved in blood, lowering the pH. Thus, venous blood, with more CO2, is more acidic and has a lower pH compared to arterial blood.
