After the flip, the volume axis will be lined up end-to-end with the zero values superimposed. you should now have a curve that looks like an "s" lying on its side and one of the graphs will be face down. hopefully your graph paper is "see through." find the ph range over which the buffer effectively neutralizes the added strong acid and strong base and maintains a reasonably constant ph. this is referred to as the buffer range. to which of the following ranges is the buffer range of the acidic buffer closest?
