Free response (2 points) part iii. finally, take the two graphs of the acetic acid solution, one of the titration with hcl and the other of the titration with naoh. place the graph of the hcl titration on top of the graph of the naoh titration. line up these two graphs along the y-axis (ph) and the x-axis (volume). flip the top graph 180°, keeping the ph axis aligned. after the flip, the volume axis will be lined up end-to-end. 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." how do these graphs compare to the graphs of the acid buffer? for example, starting at the ph in the middle of "s" curve of each graph, compare how much hcl or naoh is added before the ph has changed by 1 unit? enter your paragraph in the text box provided.
