Aqueous solution of copper sulphate does not show Tyndall effect, while the mixture of water and milk shows Tyndall effect. |
|
Answer» Solution :Colloids are big enough to scatter a beam of LIGHT passing through it. Copper sulphate solution is a true solution. The diameter of solute particles in it is LESS than 1 nm. The diameter of solute particles in solution of water and MILK is up to 1 nm to 100 nm. So this mixture is a colloidal solution. Hence, aqueous solution of copper sulphate does not show Tyndall effect but the mixture of water and milk shows Tyndall effect. |
