Which piece of laboratory apparatus is most appropriate for accurately measuring 25.0 mL of a liquid for a titration?
Show the answer and explanation
Correct answer
C. A 25 mL volumetric pipette
Principle or equation
Volumetric pipettes are designed to deliver a precise volume, with high accuracy, suitable for titrations.
Why this answer is correct
A volumetric pipette is calibrated to deliver a specific volume with high precision. Beakers and graduated cylinders have lower accuracy.
Example
In an acid-base titration, a 25.00 mL pipette is used to measure the aliquot of analyte.
