WebThere are a number of differences between the titration curves for a strong acid versus the weak acid. Weak Acid Titration The weak-acid solution has a higher initial pH. The pH rises more rapidly at the start, but less rapidly near the end point. The pH at the equivalence point does not equal 7.00 (pH > 7.00) for the weak acid titration. PURPOSE WebJul 19, 2024 · The initial pH of the solution indicates a weakly acidic solution. A strong base is the titrant as the large, final pH indicates. The equivalence point is at a pH > 7.

WebThe titration curve of acetic acid. The molecular species that predominate at low and high pH are shown. At low pH (high [H ]), the molecule is proton-ated and has zero charge. As alkali is added, the [H+] decreases (H+ + OH" - H20), acetic acid dissociates, and the carboxyl group becomes negatively charged. WebThe photo- tropic curve is from Shropshire and Withrow (1958) for Avena.
