Question

A student completes this experiment using a dirty pipet. He does not notice that several drops of liquid remain in the pipet each time it is used. How would this affect the determination of the volume of the pipet

Answer 1

The volume is less than the expected volume

Step-by-step explanation:

The pipet is a graduated instrument that is suitable for measuring and transferring a small volume of liquid.

Usually, all the liquid in a pipet should be transferred when a pipet is used to measure the volume of a liquid.The pipet should be kept clean and no drop of liquid should be left in the pipet if its volume is to be accurately measured. If the pipet is dirty and there are several drops of liquid left in the pipet, the measurement of the volume of the pipet is now inaccurate and less than the accurate volume of the pipet.
