Titration Reactions

Question 1

Which of the following would be the best reason to use titration for monitoring the effects of acid rain on drinking water?

Revolt · Accepted Answer

to determine the concentration of acid in drinking water

Question 2

Terry, a student, performs a titration. He completes these steps as part of his titration procedure:1. He cleans and rinses a burette with standardized base.2. He fills the burette with standardized base solution.3. He reads and records the initial burette volume.4. He adds a base from the burette to an acid.5. He observes a color change in the Erlenmeyer flask.6. He stops the addition of base from the burette. 7. He reads and records the final burette volume.Which steps will provide information needed to calculate the volume of base needed to reach the equivalence point?

Revolt · Accepted Answer

3 and 7

Question 9

Which of the following is the main reason to use titration in chemistry?

Revolt · Accepted Answer

to find the molarity of an unknown acid or base

Question 10

A base is added to an acid during a titration. A pH meter is used to monitor the reaction’s progress. When should the addition of base stop?

Revolt · Accepted Answer

when adding a few drops of base causes a large increase in pH
