  • APasteur pipette
  • BSyringe
  • CBalance
  • DMicropipette
  • EVolumetric pipette

Q3:

A reaction is to be performed in 100 mL of chloroform stored under air. Which piece of apparatus should be used to measure this volume?

  • ABalance
  • BMicropipette
  • CSyringe
  • DBeaker
  • EMeasuring cylinder

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
  • BSyringe
  • CMeasuring cylinder
  • DBalance
  • EMicropipet

Q5:

A student uses a micropipette 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?

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

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?

  • AHalfway between the top and the bottom of the meniscus
  • BThe bottom of the meniscus
  • CThe nearest graduation above the liquid level
  • DWhere the meniscus meets the walls of the container
  • EThe nearest graduation below the liquid level
