A solution is made by mixing equal volumes of 0.200 M HC₂H3O2 and 0.400 M NaC₂H3O2. Which of the following correctly describes what occurs if a small amount of HCI (aq) or NaOH (aq) is added? If HCI (aq) is added, the pH will increase only slightly because the Cl- ions will react with C₂H3O2 ions. If NaOH (aq) is added, the pH will decrease only slightly because the OH- ions will react with HC₂H3O2. If NaOH (aq) is added, the pH will increase only slightly because the OH ions will react with the C₂H3O2- ions. If HCI (aq) is added, the pH will decrease only slightly because the H+ ions will react with C₂H3O2 ions.
