1.	How do you observe the diffusion of copper sulphate in water? Write your findings.
Answer» Keep a small crystal of copper sulphate in the center of the petridish with the help of a forceps. Carefully fill the petridish with water. Observe the movement of blue colour in the petridish every minute. Also observe the spreading of colour from centre to periphery. Observations : 1. Copper sulphate crystal starts dissolving in water. 2. The water around the crystal will appear in blue color. 3. As time progresses, all the water in the beaker becomes coloured. 4. Initially pale blue in colour and slowly all the water in the beaker becomes uniformly blue in color. Diffusion : The copper sulphate molecules move from higher concentration to lower concentration in water through diffusion.

Answer»

Keep a small crystal of copper sulphate in the center of the petridish with the help of a forceps.
Carefully fill the petridish with water.
Observe the movement of blue colour in the petridish every minute.
Also observe the spreading of colour from centre to periphery.

Observations :

1. Copper sulphate crystal starts dissolving in water.

2. The water around the crystal will appear in blue color.

3. As time progresses, all the water in the beaker becomes coloured.

4. Initially pale blue in colour and slowly all the water in the beaker becomes uniformly blue in color.

Diffusion :

The copper sulphate molecules move from higher concentration to lower concentration in water through diffusion.
