What is the pH of each solution?

[H3O+] = 4.78 x 10-2 M
and
pOH = 4.56

Answer:

First solution pH = 1.32

Second solution pH = 9.44

Explanation:

For the first solution:

  • [H₃O⁺] = 4.78 x 10⁻² M

Which is the same as saying 4.78 x 10⁻² M is [H⁺].

Knowing [H⁺], we can now calculate the pH:

  • pH = -log[H⁺]
  • pH = 1.32

As for the second solution, we can calculate the pH by keeping in mind the relationship between pOH and pH:

  • pOH + pH = 14
  • 4.56 + pH = 14
  • pH = 9.44
