Question

From a quick eyeballing of the polyvalent titration curve, which areas are likely equivalence points and why?

a. The points with the steepest slope, as they indicate rapid pH changes during the titration.
b. The flat regions where the pH remains constant, indicating buffering capacity.
c. The regions with the highest or lowest pH values, indicating the start and end points of the titration.
d. The equivalence points are going to be near areas where there is a marked change in pH.

Answer 1

Equivalence points in a polyvalent titration curve are regions with the highest or lowest pH values, indicating the start and end points of the titration. They are also near areas with a marked change in pH.

Step-by-step explanation:

The equivalence points in a polyvalent titration curve are likely to be the regions with the highest or lowest pH values. These points indicate the start and end points of the titration. The pH at these points represents the complete neutralization of the acid and base. Additionally, the equivalence points are usually located near areas where there is a marked change in pH, such as steep slopes.
