A 1.0-L buffer solution contains 0.100 mol acid, HA, and 0.100 mol base, NaA. The value of K, for the acid HA is 1.8x104. Ignoring the small volume change, what is the most likely pH of the solution if a 10.0 mL- sample of 1.00M HCI is added to the original buffer? O 1.20 < pH < 1.45 く O 5.50 < pH < 5.74 O 4.10 < pH < 4.22 O 3.51 < pH < 3.69
