Object:
To demonstrate the phenomenon of diffusion.
Requirements:
ADVERTISEMENTS:
Beaker, water, copper sulphate crystals.
Method:
Take a clean beaker and fill it completely with water. Place a big crystal of copper sulphate on one side of the beaker (Fig. 1).
Observations:
ADVERTISEMENTS:
After some time, crystal of copper sulphate disappears and its particles get equally distributed throughout the water.
Results:
Molecules of the copper sulphate move from the region of higher concentration, i.e., crystal, to the region of lower concentration, i.e., water, and thus show the phenomenon of diffusion.
