Document Summary
Table 1: titration results of titrating unknown with naoh. Table 2: titration results of titrating hcl with naoh. 7. 14: the ph at equivalence point for the titration of hcl with a strong base naoh is 7 (found by looking at my graph) and the volume added at this point is 24 ml. The number of moles at equivalence point is equal for the base (naoh) and acid (hcl), Figure 1: a graph showing relation between volume of naoh and ph when hcl is titrated: the ph at equivalence point is 8 and the volume of base (naoh) added at this point is. Figure 2: a graph showing relation between the volume of base used and its ph. Figure 3: derivative plot graph for the unknown. The number of moles at equivalence point is equal for the base (naoh) and the unknown acid, thus the concentration is: 5 species are: a- h3o+ oh- ha na: kw = [h3o+][oh-, ka = [a-][h3o+]/[ha]
