2. What is the difference between the end point of an acid–base titration and the equivalence point?
a. There is no difference; these are just two terms meaning the same thing.
b. At the end point, the acid and base are present in equal numbers of moles. At the equivalence point, the indicator changes color.
c. The end point is always at pH 7 but the equivalence point can be at various pH values.
d.The end point can be at various pH values but the equivalence is point always at pH 7.
e. At the end point, the indicator changes color. At the equivalence point, the acid and base are present in equal numbers of moles
