1.	Observe the diffusion of potassium permanganate in water. Write your findings.
Answer» Keep a crystal of KMNO (Potassium permanganate) in the centre of the petridish with the help of a forceps. Carefully fill the petridish with water. Observe the movement of pink colour in the petridish every minute. Also observe the spreading of colour from centre to periphery. Observations: 1. Potassium permanganate crystal starts dissolving in water. 2. The water around the crystal will appear in pink colour. 3. As time progresses all the water in the beaker becomes coloured. 4. Initially pale in colour and slowly all the water in the beaker become uniformly pink coloured. Diffusion : The permanganate molecules moves from higher concentration to lower concentration in water through diffusion.

Answer»

Keep a crystal of KMNO (Potassium permanganate) in the centre of the petridish with the help of a forceps.
Carefully fill the petridish with water.
Observe the movement of pink colour in the petridish every minute.
Also observe the spreading of colour from centre to periphery.

Observations:

1. Potassium permanganate crystal starts dissolving in water.

2. The water around the crystal will appear in pink colour.

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

4. Initially pale in colour and slowly all the water in the beaker become uniformly pink coloured.

Diffusion :

The permanganate molecules moves from higher concentration to lower concentration in water through diffusion.
