Question

difference between colloids, solution,mixture,precipitate,sol

Answer 1

SOLUTIONS

A solution is a homogeneous mixture of two or more components. The dissolving agent is the solvent. The substance which is dissolved is the solute. The components of a solution are atoms, ions, or molecules, which makes them 10-9 m or smaller in diameter.

Example: Sugar and Water

SUSPENSIONS

The particles in suspensions are larger than those found in solutions. Components of a suspension can be evenly distributed by a mechanical means, like by shaking the contents, but the components will settle out.

Example: Oil and Water

More Examples of Suspensions

COLLOIDS

Particles intermediate in size between those found in solutions and suspensions can be mixed such that they remain evenly distributed without settling out. These particles range in size from 10-8 to 10-6 m in size and are termed colloidal particles or colloids. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium.

Example: Milk

Mire Examples of Colloids

MORE DISPERSIONS

Liquids, solids, and gasses all may be mixed to form colloidal dispersions.

Aerosols: solid or liquid particles in a gas.
Examples: Smoke is solid in a gas. Fog is a liquid in a gas.

Sols: solid particles in a liquid.
Example: Milk of Magnesia is a sol with solid magnesium hydroxide in water.

Emulsions: liquid particles in a liquid.
Example: Mayonnaise is oil in water.

Gels: liquids in solid.
Examples: gelatin is protein in water.

Quicksand is sand in water.

TELLING THEM APART

You can tell suspensions from colloids and solutions because the components of suspensions will eventually separate. Colloids can be distinguished from solutions using the Tyndall effect.

Answer 2

Explanation:

• Particles of a solute that are microscopically and uniformly dispersed in a solvent is known as a colloid.

For example, milk is a colloid.

• Solution is defined as the homogeneous mixture in which two or more solute particles uniformly distribute in a solvent resulting in the formation of a clear solution is known as a solution.

For example, dispersion of ink in water.

• A mixture is defined as the combination of two or more different substances which are not chemically combined to each other. When solute particles are present uniformly into the solvent then it is known as a homogeneous mixture.

For example, sugar dissolved in water.

• When solute particles are unevenly distributed into the solvent then it is known as a heterogeneous solution.

For example, sand in water.

• A precipitate is defined as an insoluble solid formed when two aqueous solutions chemically combine to each other.

For example, $AgNO_{3}(aq) + HCl(aq) \rightarrow AgCl(s) + HNO_{3}(aq)$

• A sol is defined as very tint solid particles that are present in continuous liquid medium.

For example, blood, paint, cell fluids etc.
