If 20.22mL of a 0.100M NaOH solution is required to reach the stoichiometric point for a strong monoprotic acid titration, what volume of 0.100M NaOH would be required to reach the stoichiometric point for a weak monoprotic acid solution of the same molar concentration? Explain
The PH at the stoichiometric points is 7.00(25 0c) for a strong acid- strong base (titrant) titration, but it is greater than 7.00 for a weak acid titration. Explain
