Question

At a pH of 7.10, the H+ concentration is equal to a. 80 nmol/L b. 20 nmol/L c. 40 nmol/L d. 60 nmol/L

Answer 1

The H+ concentration at a pH of 7.10 is approximately equal to:

c. 40 nmol/L

In a neutral solution (pH 7), the concentration of H+ ions is 10^(-7) mol/L. Since the pH is slightly above 7 (pH 7.10), the H+ concentration is slightly less than 10^(-7) mol/L. Converting this to nanomoles per liter (nmol/L), we get approximately 40 nmol/L.
