Question

Determine the pH of a 0. 023 M HNO3 solution. A) 12. 36 B) 3. 68 C) 1. 64 D) 2. 30 E) 2. 49

Answer 1

To find the pH solution, you need to use the equation ph= -log [H], where [H] is the molarity or molar concentration of the acid.

HNO3, or nitric acid, is an acid, so this equation will work perfectly in finding your answer.

You have been given the molarity of the nitric acid in this solution: 0.023 M

All you have to do is plug in the molarity of HNO3 into your equation and solve using your calculator:

pH= -log(0.023)

pH≈1.64

Your answer is C
