pls answer part 1,2,3 pls need help Titration Lab Procedure: Name Part 1 : Take the titration lab data and graph each data set for Ph vs. Vol NaOH. The biggest changes in ph vs. vol NaOH indicate endpoints. Use your notes to write down the net ionic equations and ph indicators for each titration. Report the three graphs for HCl + NaOH, H,PO, and NaOH, and CHCOOH and NaOH. Part 2 Pka Estimation. Once you have found each endpoint,...

Question: In the figure below, titration curves for strong acid with strong base and weak acid with strong base are shown. Compare the shapes of these curves early in the titration for three different cases: titration of a strong acid, titration of a weak acid with a lower pKa, and titration of a weak acid with a higher pKa. Discuss with the class why the titration curve for weak acids increase more rapidly early in the titration than do stronger...
