Question

1.Why a mixture is an impure substance?
2. Define aerosol.
3. What is meant by solubility of a solute?
4. How to differentiate between sol, solution and suspension .​

Answer 1

Answer:

1. A mixture is an impure substance. It consists of different elements and substances combined together physically in an unknown ratio. ... A mixture doesn't have a definite boiling or freezing point. All these properties of a mixture make it an "Impure substance".

Explanation:

2..An aerosol (abbreviation of "aero-solution") is a suspension of fine solid particles or liquid droplets in air or another gas. Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog, mist, dust, forest exudates and geyser steam.

3. .Solubility. Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.

4. The key difference between sol solution and suspension is that the particles in a sol have dimensions around 1 nanometer to 1 micrometre and a solution has particles with dimensions below 1 nanometer whereas a suspension has particles with dimensions higher than 1 micrometre.
