Worksheet: Measurement Apparatus

In this worksheet, we will practice describing measurement apparatus, comparing their uses and precision, and assessing their suitability.

Q1:

  • ESyringe

Q4:

A reaction is to be performed in approximately 10 mL of a dry solvent. Which piece of apparatus should be used to measure this volume?

  • AVolumetric pipet
  • BMicropipet
  • CBalance
  • DSyringe
  • EMeasuring cylinder

Q5:

A student uses a micropipet to transfer a liquid to a flask but finds that the weight of the liquid is less than expected. Which of the following is not a likely cause of the problem?

  • ABubbles were present in the pipetted liquid.
  • BLiquid has evaporated from the flask.
  • CThe volume of the micropipet was set incorrectly.
  • DThe viscosity of the liquid is too low.
  • EThe plunger of the micropipet was raised too quickly.

Q6:

The diagram illustrates the use of a measuring cylinder to determine the volume of a liquid. From which point should the reading be taken?
