3. Which acid would you choose to combine with its sodium salt to make a solution buffered at pH 4.25? For the best choice, calculate the ratio of the conjugate base to the acid required to attain the desired pH. Chlorous acid pKa = 1.95 Nitrous acid pKa = 3.34 Formic acid pKa = 3.74 Hypochlorous acid pKa = 7.54
