Question

do anyone have practical of chromatography and diffusion of class 11th​

Answer 1

Hey mate,...

Practical of Diffusion:-

Requirements:

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).

Diffusion phenomenon

Observations:

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.

Hope it will help you.

Answer 2

CHROMOTOGRAPHY :-

practicle of chromotography requires beaker, water, copersulphate, crystal

Take a big beaker and put a piece if coppersulphate on the water.

then u will find the duffision kf copersulphate on water at a slow process.

DIFFUSION:-

After giving the crystal of coppersulphate u will find the blue colour of coppersulphate get spread over the whole water due to the movement of molecules.

HOPE ITS HELP YOU
