I. A titration is the progressive addition of one reagent to another.
II. A titration involves a chemical reaction between an acid and a base.
III. The indicator endpoint shows that chemically equivalent amounts have been brought together.
IV. A titration results in a solution with a pH of 7.0 at the equivalence point.
Regarding titrations, which of the above statements are always true?
a. I and II
b. I and III
c. II and III
d. I, II, III, and IV
Titration is a classic analytical method during which a standard reagent is slowly added to a sample containing an unknown solution until the reaction is judged complete. The neutralization point is often indicated by a color transition, color disappearance, color development, and/or precipitation.
