Consider how to prepare a buffer solution with pH= 3.11 (using one of the weakacid/conjugate base systems shown here) bycombining 1.00 L ofa 0.320-M solution of weak acidwith 0.231 M potassiumhydroxide.
HNO2
NO2-
4.5 x 10-4
3.35
HClO
ClO-
3.5 x 10-8
7.46
HCN
CN-
4.0 x 10-10
9.40
How many L of the potassiumhydroxide solution would have to be added to the acidsolution of your choice?
