If, during a metabolic acidosis the pH falls to 7.1, and the (HCO3) falls to 12 meq/L, the total conc. of H+ ions neutralized by the (HCO3)/(CO2) buffer system as the metabolic acid is titrated is approx.:

Answers: 6.0 meq/L, 12.0, 14.5, 18.0, 24.0.

The correct answer is approximately 12.

pH is a measure of the "hydrogen ion" content of water and, therefore, of its acidity. Neutral water which is neither acidic nor basic has a pH value of 7. A pH lower than 7 indicates acidity. And a pH higher than 7 indicates basicity. pH is defined as log/aH+

In this problem, pH = 7.1 and (HC03) = 12 meg/L

Let x = the total concetration of H + ions

When neutralized, pH = 7

Therefore,

7.1/12 = 7/ x

x=11.83

The answer is 11.83 or approximately 12 meq/L
