Calculate the pH and pOH of a 0.25 M NaOH solution

Question

Calculate the pH and pOH of a 0.25 M NaOH solution. • Are you working with an acid or a base? ____________ • Are you given the concentration, or Molarity of that solution? ____________ • Next, plug the concentration or Molarity into the correct equation. Because this is a basic solution, we have to calculate pOH first. pOH = − log[0.25] = ___________________ Now we can calculate the pH, because we have calculated the pOH. pH = 14 − pOH = _______________ = _______________
