Which is the best definition of the equivalence point for an acid-base titration? The equivalence point is when the concentration of the acid is equal to the number of moles of base. The equivalence point is when the solution turns from pink to clear. The equivalence point is when the solution turns from clear to pink. The equivalence point is when the number of moles of titrant added equals the number of moles of sample being titrated. The equivalence point is when the volume of titrant added equals the volume of the solution being titrated. O O O O

Determine the pH during the titration of 20.6 mL of 0.328 M perchloric acid by 0.206 M barium hydroxide at the following points:a.Before the addition of any barium hydroxide b.After the addition of 8.20 mL of barium hydroxide c. At the equivalence point d. After adding 20.8 mL of barium hydroxide
You have an unknown solution whose initial pH is 2.90. Addition of 10 ml of the titrant increased the pH to 4.15. Adding small-volume increments of the titrant causes the pH to increase very slightly. At equivalence point, the pH of the solution is at 8.70. Abrupt increase in pH to 10.00 was observed when 0.1 ml of titrant was added after equivalence point. Addition of few more drops of the titrant just increase the pH even more with no buffering region. Which among the choices best describes the analyte? The analyte is a strong monoprotic acid. The analyte is a weak monoprotic acid. The analyte is a weak monoprotic base. O The analyte is a weak diprotic acid. O The analyte is a weak diprotic base.
Explain how to choose the appropriate acid-base indicator for the titration of a weak base with a strong acid.
why are equivalence points on a titration graph equally spaced along the horizontal axis?

Use the following two titration curves to answer each of the following statements. Select the choice that completes the statement correctly. 14 pH 7 0 Graph A 25 volume of titrant added (mL) In graph A, the end point occurs at a In graph B, the equivalence point occurs at a + 141 pH 7 0 Graph B 25 volume of titrant added (mL)
Why do scientists want to find the equivalence point in a titration? a) To form a colored compound that can be used as a pigment b) To find the pH of an acid-base solution c) To determine the unknown concentration of a compound that reacts with another of known concentration
In general changing the color of solution only represent the end point of titration. O True O False
In titrations that involve strong acids and weak bases, the equivalence point should have a pH that is a) Acidic b) Basic c) Neutral d) More information is required
In a titration between strong acid and strong base, what is the pH of the solution when its color changed? It will be exactly at end point and the pH is more than 7. It will be exactly at end point and the pH is exactly 7. The pH at end point depends on which solution is the titrant. It will be exactly at equivalence point and the pH is exactly 7.
