Calculate the pH for each case in the titration of 50.0 mL of 0.220 M HCIO(aq) with 0.220 M KOH(aq). Use the ionization constant for HCIO. What is the pH before addition of any KOH? pH = || What is the pH after addition of 25.0 mL KOH? pH What is the pH after addition of 40.0 mL KOH? pH =

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+
