Final answer:

The pH of an acid solution containing 0.039 M HNO3 is 1.41.

Step-by-step explanation:

The pH of an acid solution is determined by the concentration of hydrogen ions ([H+]). In this case, the acid solution contains 0.039 M HNO3. Since HNO3 is a strong acid, it completely dissociates in water to yield H+ ions. Therefore, the concentration of H+ ions in the solution is equal to the concentration of HNO3, which is 0.039 M.

To calculate the pH of the solution, take the negative logarithm (base 10) of the H+ concentration: pH = -log[H+]. Substituting the concentration value, we get: pH = -log(0.039) = 1.41.

Therefore, the correct answer is c. 1.41
