In the following example, by changing the titration conditions on a weak acid as compared to a strong acid, a difference at the pre-equivalence regions for the two is evident, while no difference at the post-equivalence regions is observed: 13. HWoak 0.50M HStrong 0.50 M HWoak 0.025 M HStrong 0.025 M pH 7- Caso A pH 7- Case B NaOH volume, ml. NaOH volumo, ml In both Case A and Case B, 0.50 M and 0.025 M acids are titrated with NaOH 0.50 M and NaOH 0.025 M, respectively. Case A corresponds to the weak acid titration (represented as HWeak) and Case B corresponds to the strong acid titration (represented as HStrong). Explain why the pH behavior in Case A is different from Case B in the pre-equivalence region when changing conditions, while they are the same in the post-equivalence region.
