The concentration of hydronium ion, H3O+, in the solution with pOH of 5.3 is 1.99 × 10-⁹M.

HOW TO CALCULATE HYDROGEN CONCENTRATION:

  • The pOH of a solution is given as 5.3. The pH of this solution can be calculated as follows:

  • pOH + pH =14

  • 5.3 + pH = 14

  • pH = 14 - 5.3 = 8.7

  • pH = 8.7.

  • The hydrogen ion concentration can be calculated by using the following expression:

  • [H+] = 10-pH

  • [H+] = 10-⁸.⁷

  • [H+] = 1.99 × 10-⁹M

Therefore, the concentration of hydronium ion, H3O+, in the solution with pOH of 5.3 is 1.99 × 10-⁹M.
