If you have two solutions, one of strong acid and one of weak acid, how do you think the amounts of H30+ ions are going to compare to the amount of undissociated acid molecules in each solution? (Remember that when we measure the pH, we are measuring how much H*- - or HO*-- is in the solution. The more H*, the more acidic the solution is.) If you have two solutions, one of strong base and one of weak base, how do you think the amounts of OH- ions are going to compare to the amount of undissociated base molecules in each solution?
