a 50. mL of aquesous CH3COOH and 25.mL of aquesous HCI
b 50. mL of quesous CH3COOH and 100. mL of aqueous NaOH
c 50. mL of aquesous NaOH and 25. mL of aqueous HCI
d 50. mL of aqueous CH3COONa and 25.mL of aquesous NaOH
e 50.mL of aqueous CH3COOH and 25.mL of aqueous CH3COONa

Thanks for any help....
