Chemistry - Measurement and Experimental Techniques

HideShow resource information

Apparatus:

Beaker: Approximate volume only, 100, 200, 300cm3 
Burettes: Accurately add to 0.1cm3
Pipette: Accurately measures fixed volume such as 20.0cm3 and 25.0cm3
Measuring cylinder: More accurate than a beaker, measures up to the nearest cm3. eg. 99cm3
Gas syringes: Used for gases!  

Collection of gas:

Depends on:
1. Solubility
2. Density of gas compared to air


Gas                       Solubility in water
