Answers
Answer:
Eye protection
Conical flask (100 cm3)
Single-holed rubber bung and delivery tube to fit conical flask (note 1)
Trough or plastic washing-up bowl (note 2)
Measuring cylinders (100 cm3), x2
Clamp stand, boss and clamp
Stopwatch
Graph paper
Apparatus notes
The bungs in the flasks need to be rubber. Corks are too porous and will leak. The tube through the bung should be a short section of glass, and then a flexible rubber tube can be connected.
Gas syringes can be used instead of troughs of water and measuring cylinders. But these are very expensive and are probably best used by the teacher in a demonstration. Syringes should not be allowed to become wet, or the plungers will stick inside the barrels.
