Question 1

Explain how to accurately weigh and transfer a solid to a beaker

Answer 1

1) Weigh the solid and a weigh-boat
2) tip into the beaker
3) re-weigh the beaker
4) subtract the two masses to find the mass added

Question 2

Explain why using distilled water to wash a reagent into a flask does not affect the titration result

Answer 2

Distilled water is neutral

Question 3

Explain how to set up a clean burette with acid in it

Answer 3

1) wash with distilled water
2) wash with acid
3) wash through the tap with acid
4) fill up with acid
5) run through the tap to make sure air bubble is removed

Question 4

What happens to a titration result if the air bubble is not removed from the tap?

Answer 4

The volume added is less than expected
