Observe the diffusion process which begins in both the beakers.5. Place the second beaker containing 100ml of water on a tripod stand for heating.4. Pour 100ml of distilled water slowly in both of the beakers.3. Take 5g of copper sulphate each in two beakers.2.

diffusion takes place.PRECAUTIONS:The beaker should be clean.The beaker should be left undisturbed.Įxperiment 2AIM :To study the effect of temperature on the rate of diffusion of solids in liquidsREQUIREMENTS: Copper sulphate crystals, 200ml beaker, burner, tripod stand and stopwatch.PROCEDURE:1. Note the blue colour change in water.CONCLUSION:When solids such as copper sulphate, potassium permanganate are brought in contact with liquids such as water, intermixing of substances, i.e. Allow to stand further till it is observed that all copper sulphate disappears.5.

Note the development of blue colour in water.4. Add about 50ml of water and allow it to stand for few minutes.3. Take about 2g of copper sulphate crystals in 100 ml beaker.2. Molecules of solute are in constant random motion due to the collision between molecules of solute and that of the solventTheoryRate of diffusion depends upon:-Temperature: As temperature increases, the kinetic energy of the particles increases so the speed of particles also increases which thus increases the rate of diffusion.Size of the particle: As the size of particle increases, rate of diffusion decreases.Mass of the particle : As the mass of the particle increases the rate of diffusion decreases.Įxperiment 1AIM :To study diffusion when copper sulphate is brought in contact with water (liquid)REQUIREMENTS: Copper sulphate crystals, 100 ml beaker.PROCEDURE:1. We know that this process is known as dissolution of a solid in liquid and this process has taken place due to the diffusion of solid particles into liquid. If a solid is kept in contact with an excess of solvent in which it is soluble, some portion of the solid gets dissolved. This property of diffusion takes place very rapidly in case of gases and to a lesser extent in case of liquids, whereas solids do not show this process of diffusion with each other.But what we can observe in case of solids is that the diffusion of solids in liquids takes place at a very slow rate. Then I would like to thank my parents who have helped me with their valuable suggestions and guidance which have been helpful in various phases in the completion of the project.Last but not the least I would like to thank my classmates who have helped me a lot.Īim - To study diffusion of solids in liquidsOverviewWhen substances are brought in contact with each other they intermix, this property is known as Diffusion. VS Phogat, whose valuable guidance has helped me a lot in making this project and make it a success his suggestions and his instructions have served as major contributor towards the completion of the project. In the accomplishment of this projects success, this time I am utilizing to thank all the people who have been concerned with the project.I would like to thank our principal Mrs. Sign of Examiner Sign of Chemistry TeacherACKNOWLEDGEMENT VS Phogat during the year 2015-16 in partial fulfillment of chemistry practical examination conducted by CBSE.
