Question

A solution of nitric acid has an H concentration of 2.50 x 10^-4 M. What is the pH of the solution?

a) pH = 4.60
b) pH = 2.50
c) pH = -2.40
d) pH = 4.40

Answer 1

The pH of a solution with an H+ concentration of 2.50 x 10^-4 M is calculated using the formula pH = -log[H+], which gives a pH value of 3.60.

Step-by-step explanation:

The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter (M).

For a solution with an H+ concentration of 2.50 x 10^-4 M, we use the given formula:

pH = -log(2.50 x 10^-4)

This calculation will give us the pH of the solution. When we compute this using a calculator, we get:

pH = 3.60 (which is not listed in the options, so there might be a typo in the question).
