Which of the following statements is true? (Multiple answers possible) Group of answer choices:
a. There is no error associated with the difference in equivalence and endpoints.
b. The endpoint does not correspond exactly to the equivalence point. c. At the endpoint, a change in a physical quantity associated with the equivalence point occurs.
d. The endpoint corresponds exactly to the equivalence point.
e. At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present. f. At the equivalence point, the amount of reagent added does not yet equal to the amount of analyte present.

The endpoint does not correspond exactly to the equivalence point

At the endpoint, a change in a physical quantity associated with the equivalence point occurs.

At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present.

Explanation:

The end point is always indicated by some physical property that changes such as colour. At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present. The equivalence point cannot be physically observed but can be deduced after a titration curve is plotted.

alfred von schlieffen, german army chief of staff, was given instructions to devise a strategy that would be able to counter a joint attack. in december, 1905, he began circulating what later became known as the schlieffen plan. schlieffen argued that if war took place it was vital that france was speedily defeated.
