chapter 1: experimental chemistry

burette measurement

2dp, measures up to 50.0cm³, accurate to 0.05cm³ (eg 26.95cm³)

pipette

very accurate set volumes, such as exactly 20.0cm³ or 25.0cm³

measuring cylinder

accurate only to the nearest cm³ (eg 20cm³, 25cm³)

beaker

approximate volume of 100cm³ or 250cm³

displacement of water

for gases that are insoluble or slightly soluble in water

downward delivery

for gases that are soluble in water and denser than air

upward delivery

for gases that are soluble in water and less denser than air
