Calculate pH and pOH of a weak acid or base solution using simple formula, quadratic equation, and including autoionization of water. Calculate the pH or pOH quickly. Weak acids and bases are only partially ionized in their solutions, whereas strong acids and bases are completely ionized when dissolved in water.
