Potassium hydroxide

KOH is a strong base meaning that it dissociates completely in solution This means that after dissolving 0 01 M of K+ and 0 01 M of OH- will be present in solution The pOH is a measurement of OH- concentration measured by -log[OH-] The pOH of this solution would be equal to -log[0 01] or 2 pOH has a relationship to pH: pOH + pH = 14

pH Calculations of Strong Bases

Calculate the pH of a 0 0010 M solution of NaOH NaOH== Na + + OH-Therefore the [OH-] equals 0 0010 M So to solve it you write: pOH = - log (0 0010) = 3 00 pH = 14 000 - 3 00 = 11 00 Calculate the pH of a 0 025 M solution of Ca(OH) 2 Ca(OH) 2 == Ca 2+ + 2OH- Therefore the [OH-] equals 0 050 M For every Ca(OH) 2 you produce 2OH- pOH = - log (0 050) = 1 70 pH = 14 000 - 1 70 = 12 30
