Question

Correct procedure for a titration includes which of the following?

Rinsing the buret before beginning your titration with the solution that you use to titrate the sample.
a) 1 only

b) 2 only

c) Both 1 and 2

d) Neither 1 nor 2

Answer 1

The correct titration procedure includes rinsing the buret with the titration solution. A buret is crucial for accurate volume delivery, and knowing the titrant concentration allows for precise analyte evaluation.

Step-by-step explanation:

The correct procedure for a titration includes rinsing the buret before beginning the titration with the solution that you will use to titrate the sample. This step ensures that the buret is free from any contaminants and that the concentration of the titrant in the buret is not diluted. Specifically, when preparing for a titration analysis, it is important to use a buret to deliver precise volume measurements, generally to the nearest 0.01 mL, for accurate titration results.

In a titration process, one reagent, known as the titrant, typically has a known concentration, while the other reagent, the analyte, has an unknown concentration. The buret is used to add the titrant to the analyte with great precision, allowing for the exact calculation of the analyte's concentration once the equivalence point of the reaction is reached. It is also crucial to add the titrant slowly to accurately determine the end point, which is indicated by a color change if an indicator is used.
