Question

what instrument is used as the reaction vessel in a titration experiment? pipette beaker burette stir bar

Explanation:

• A pipette is used to measure and transfer precise volumes of liquid, not as a reaction vessel.
• A beaker can hold the solution being titrated (the analyte) and is a common reaction vessel in titration as the titrant is added to it.
• A burette is used to deliver the titrant (the solution of known concentration) in a controlled manner, not as the reaction vessel.
• A stir bar is used to stir the solution, not as a reaction vessel.
