Which tool is used to pipette a precise volume to prepare a standard solution?

• A. Volumetric Flask
• B. Pipette
• C. Beaker
• D. Graduated cylinder

Answer: (B)

Transferring an exact amount of liquid is the job of a pipette. It’s designed to draw up and dispense a defined volume, which is essential when preparing a standard solution because the final concentration hinges on delivering a precise amount of liquid. In practice, you use the pipette to add that exact volume into the receiving vessel (often a volumetric flask), then fill to the marked line to reach the correct total volume. A beaker is for rough handling and mixing, not precise measurements; a graduated cylinder offers better accuracy than a beaker but still isn’t as precise as a pipette for transferring a specific volume; a volumetric flask sets the final volume but isn’t itself the tool used to pipette the precise amount into the flask.
