Question

In this experiment, we will need to ensure the sample and burette are ready for titration. Which of the following statements are true?

1) The sample should be properly prepared before titration
2) The burette should be clean and dry before titration
3) The sample and burette should be at the same temperature before titration
4) The sample and burette should be shaken before titration

Answer 1

In a titration experiment, the sample should be prepared properly, the burette should be clean and dry, and the sample and burette should be at the same temperature.

Step-by-step explanation:

In a titration experiment, there are several important steps to ensure accurate results.

1. The sample should be properly prepared before the titration, which may involve filtering or diluting it if necessary.
2. The burette should be clean and dry before the titration to prevent any contamination or inaccurate measurements.
3. The sample and burette should be at the same temperature before the titration to ensure consistent results.

Shaking the sample and burette before the titration is not necessary.
