1. What is the difference between an end point and an equivalence point?
2. Table 1 lists several indicators that are commonly used along with their equivalence points and the color change that accompanies the reaction. Review the information, and answer the questions below.
a. Suppose a titration was performed in which a base of pH 6 was being titrated. The equivalence point of the titration was at pH near 8. What indicators should be added to the base solution before the titration is carried out?
b. What is the color of the basic solution before any acid is added?
c. What is the color of the solution after the equivalence point is reached at a pH of 8?
