Microscale Chemistry Experimentation for Teachers
6.
Syringes as microscale measuring cylinders: Density of aluminium
*
Remove the piston of a 1-ml syringe.
* Heat the nozzle
carefully until it is soft.
* Close the syringe
by pressing the soft plastic
with
tongues.
* Half-fill the self-made measuring cylinder
by coloured water,
* read the volume (photo: 0.6 ml)
* Add pieces of aluminium wire to the
water.
* Read the volume of water replaced by
the metal (photo: 0.82 - 0.60 ml).
