Question

Which of the following statement(s) is/are false regarding color indicators? Choose all that apply. A color indicator will always change color exactly at the equivalence point of the titration. Color indicators are used in titrations to signal the completion (or neutralization) of an acid-base reaction. A color indicator is most effective over a large pH range. Color indicators are typically weak acids or bases themselves. Color pH indicators are usually complex organic molecules that are weak acids or bases. Which of the following statements seems reasonable given your understanding of this topic? A pH color indicator molecule interacts with light dependent on chemical structure, switching from one structure when protonated (acidic hydrogen attached) to another structure when de-protonated. All pH indicators switch colors at the same pH. When used in a titration, a color indicator is chosen that will switch from one color to another before the equivalence point is reached.
