using gas syringe

Question 1

when would we use this experiment?

Answer 1

-measuring the volume of gas
- work out moles of gas
(use ideal gas equation)

Question 2

what are the potential errors in a gas syringe?

Answer 2

• gas escapes before bung is inserted
• syringe sticks
• some gases e.g. CO2 and SO2 are soluable in water so true amount of gas is not measured

Question 3

what do you not forget when drawing a diagram of a gas syringe experiment?

Answer 3

• gas syringe should have measurement markings on the barrel

- no gaps where gas could escape
