I need help with both answers. Thank you. < Question 29 of 65 > A buffer is prepared by mixing hypochlorous acid (HCIO) and sodium hypochlorite (Nacio). If a strong acid, such as HCl, is added to this buffer, which buffer component neutralizes the additional hydrogen ions (H)? CIO OHCIO. Write a balanced chemical equation for the reaction of the selected buffer component and the hydrogen ion (H+). Do not include physical states. chemical equation:
