Quizplus · Accepted Answer

pH is defined as the negative logarithm (base 10) of the hydrogen ion concentration in a solution. Therefore, pH equals the logarithm to the base 10 of the reciprocal of the hydrogen-ion concentration (A). The Henderson-Hasselbalch equation can be used to calculate pH if the HCO3- and CO₂ concentration in the body fluids is known, even if the H+ concentration is unknown (B). Arterial blood has a higher pH than venous blood because it contains more oxygen and less carbon dioxide (C).
