Question

IUS. A 21.54-mL volume of 0.130 M NaOH is required to reach the stoichiometric point for the titration of 25.00 mL of a 0.112 M HCl solution. Would the titration of 25.00 mL of a 0.112 M CH3COOH solution require more, less, or the same volume of the 0.130 M NaOH solution? Explain. 6 - -

Answer 1

It requires less volume of NaOH for titration of acetic acid as compared to HCl as HCl is a strong acid which dissociates completely whereas acetic acid is a weak acid which won't dissociate completely. So H+ ion concentration in case of acetic acid will be less than that of H+ ion concentration of HCl . So less volume of NaOH solution is needed.
