A student was required to prepare 250.0 mL of a hypochlorous acid/sodium hypochlorite buffer in which the concentration of the weak acid component was 0.084 M and the concentration of the conjugate base was 0.02 M. The student was supplied with 0.441 M hypochlorous acid and 1.0M NaOH to perform this task. What volume (in mL) of the acid would the student need to prepare this buffer solution? Hint: assume that all of the conjugate base comes directly from the reaction of NaOH with the weak acid (in other words, there is negligible dissociation of the weak acid).

The weak acid of the buffer system is used to prepare the buffer by reacting with a strong base. The conjugated base is going to be obtained from some of the weak acid in reaction with NaOH 1M. This means you need to calculate the total amount of weak acid needed and the amount of 1.00 M NaOH solution you will have to add to create its conjugate form in solution.   Use 1.0M of each of these acids and basic...
