One beaker contains 10.0 mL of acetic acid/sodium acetate buffer at maximum buffer capacity, and another contains 10.0mL of pure water. Calculate the hydronium ion concentration and the pH after the addition of .25mL of .10 M HCl to each one. What accounts for the difference in hydronium ion concentrations? Explain this based on equilibrium concepts.
Ka of acetic acid= 1.8*10-5
Acetic Acid/Sodium acetate buffer
Acetic acid .1M
Sodium Acetate .1M
