Answer» Explanation: a) (I) SOLUTION :- + A homogeneous mixture of two or more substances is called Solution. + It has 2 major COMPONENTS and they are : Solvent & Solute. EXAMPLES :- A) SUGAR AND SALT SOLUTION B) DUST FREE AIR C) BRASS (II) SUSPENSION :- + A heterogeneous mixtures of insoluble particles of solute, spread throughout a solvent is called Suspension. + The size of particles is more than 10^-5 cm in diametre. + The particles of suspension can be separated from.solvent by the process of filteration. EXAMPLE :- A) MUDDY WATER B) SLAKED LIME WATER C) PAINTS. (III) COLLOIDS:- + Heterogeneous nature. + The size of particles of colloids of 10^-9 to 10^-7 cm. + Separation of colloidal particles by centrifugation. + Stability EXAMPLE :- A) MILK B) FOG C) SMOKE b) Suspension will show the tyndall effect because the BIG size of particles can be seen from the microscope.And when we show a torch in the solution the light scatters due to the big size of particles and show tyndall effect. I HOPE IT WILL HELP YOU. And if it helped then please mark it as the brainliest answer.plz.
