Question

Describe the properties of solutions, colloids and suspensions​

Answer 1

Explanation:

Suspensions are a heterogeneous mixture of two or more substances.

Particles of the solute do not dissolve in the solvent rather they remain suspended in bulk throughout.

The size of particles of suspension is large enough to be visible from naked eyes.

Stability: Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution. Filterability: Colloids require specialized filters known as ultrafilters for filtration.

Solutions

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

Explanation:

A suspension is defined as a heterogeneous mixture in which the solid particles are spread throughout the liquid without dissolving in it.

Properties of Suspension :

• A suspension is a heterogeneous mixture.
• The size of solute particles in a suspension is quite large. It is larger than 100 mm in diameter.
• The particles of a suspension can be seen easily.

• The particles of a suspension do not pass through a filter paper. So a suspension can be separated by filtration.

• The suspension is unstable. The particles of a suspension settle down after some time.

• A suspension scatters a beam of light passing through it because of its large particle size.

examples  :

• Muddy water

• Milk of magnesia

Colloids (also known as colloidal solutions or colloidal systems) are mixtures in which microscopically dispersed insoluble particles of one substance are suspended in another substance.

properties of colloids:

• Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution.
• Colloids require specialized filters known as ultrafilters for filtration. They readily pass through ordinary filter papers without yielding any residue.
• Since colloids consist of two phases, the dispersed phase as well as the dispersion medium, they are known as heterogeneous in nature.
• Even though colloids have suspended particles and are heterogeneous in nature, they appear as if it is a homogenous solution. This is because the suspended particles are so tiny that they are not visible by the naked eye.

examples :

• fog, smog, and sprays
• smoke and dust in the air

Solutions are a homogeneous mixture of two or more substances.

properties of solutions:

• A solution is a homogeneous mixture of two or more substances.
• The particles of solute in a solution cannot be seen by the naked eye.
• A solution does not allow beams of light to scatter.
• A solution is stable

• The solute from a solution cannot be separated by filtration (or mechanically)

examples:

• salt water
• rubbing alcohol
