Answer» Answer: ASSERTION and the Reason both are correct but the reason is not the explanation of assertion. Explanation: True SOLUTION :-A solution in which the particle SIZE of the solute is 10 - 9 m or 1 nm. completely dissolves in the solvent is called a true solution. Ex :- Sugar solution,Salt solution,Air etc. Colloidal solution :-A solution in which the particle size of the solute is 1 - 1000nm. The solute PARTICLES are evenly suspended in the solvent. Ex :- Milk,Blood, Shaving cream etc. Suspension :-The solution in which the two substances doesn't dissolve in each and The particles settle down after SOMETIME. Ex :- Chalk in water,Mud in water etc. Hope it helps |
