What is the pH after adding 10.0 mL of 0.10 M HCl to a 90.0 mL buffer solution of 0.60 M CH3COOH and 0.40 M CH3COONa at 25 °C? (Ka = 1.8 x 10−5)? What reaction will occur when HCl is added to the above buffer?
1) How many moles of acetic acid are present after the reaction?
2) How many moles of acetate ion are present after the reaction?
3) What is the concentration (in M) of acetic acid after the reaction?
