Beaker ′A′ has chalk powder mixed with water and beaker ′B′ has protein dissolved in water.
i) Which solution shows Brownian movement?
ii) Identify the solution that has the particle size greater than 2000∘A.
iii) Which beaker contains colloidal solution?
iv) Mention the size of the particle present in beaker B.
v) Say whether colloidal solution in homogeneous or heterogeneous
Beaker A has chalk powder not completely dissolved in water.
Beaker B has protein in water which is a colloidal solution.
(i) The Brownian movement will be shown by colloidal solution in Beaker B.
(ii) Particle size is greater than 2000oA for solution having less soluble solute. This is applicable for Beaker A.
(iii) Protein in water i.e. Beaker B has a colloidal solution.
(iv) Beaker B has a particle size in colloidal range i.e. 1 to 100nm.
(v) A colloidal solution is heterogeneous as the components do not get completely mixed, and that such a solution is not transparent.
