Consider a buffer solution prepared by adding 0.45 mol of CH3COOK to 1.00 L of 2.00 M CH3COOH. (K₁ = 1.8 x 10-5). If 0.05 mol of HCI is added to this buffer solution the pH of the solution will drop slightly. The pH does not drastically decrease because the HCI reacts with present in the buffer solution. Select one: O a. H₂O O b. CH3COOH O C. CH3COO O d. H+
