Please answer both questions. 24. Calculate the percent ionization for a 0.0240 M hypochlorous acid solution. The ka for hypochlorous acid is 3.4x10-8 27. A chemist wants to make a pH 7.29 buffer. Two chemical combinations are available: hypochlororous acid (HCIO, K, = 3.5x10%) with sodium hypochlorite, or sodium dihydrogen phosphate (NaH2PO4, K. = 6.2x10") with sodium hydrogen phosphate. Which chemical combination is best for the buffer? What [base]/(acid) ratio should be used?
