Question

A lab uses nitric acid to determine the amount of minerals in a soil sample. What is the pH of the nitric acid used if it has a molarity of .001M?

Answer 1

We are given a compound, nitric acid which is used to determine the amount of minerals of a soil sample. The pH of the nitric acid used if its molarity is 0.001M is:

pH = -log[0.001]
pH = -[-3]
pH = 3

Therefore, the pH of the nitric acid is 3.
