Webb14 maj 2024 · Since KOH and OH - are in a 1:1 ratio, [KOH] = [ OH - ], so 0.033 M KOH = 0.033 M OH - The concentration of [ OH - ] can then be used to calculate the pOH of the solution. pOH = -log [ OH - ] = -log (0.033) = 1.48 This relationship between pH and pOH can then be used to find the pH: pH + pOH = 14 pH = 14 - pOH = 14 - 1.48 = 12.52.
