Question

what is the different between solution suspension and colloid ​

Answer 1

The difference between solution, suspension, and colloid are as follows:

• Solution is a homogeneous mixture while suspension and colloid is a heterogeneous mixture.
• The size of particles, in a solution, is less than 1nm in size, particles, in a suspension are larger than 100nm, while particles in a colloid are neither small nor big and are in between 1nm to 100nm in size.
• Particles in a solution do not settle down when left undisturbed so do the particles in a colloid, but on the other hand, the particles in a suspension settle down when left undisturbed.
• An example of a solution is brine water, an example of a suspension is sand and water and an example of a colloid is blood.

Answer 2

The following are the differences between a solution, suspension, and colloid:

→ The solution is a homogeneous mixture while suspensions and colloids are heterogeneous mixtures.

→ We can differentiate solution, suspension and colloids on the basis of the size of the solute particles:

• The size of particles, in a solution, is less than 1 nm in size.
• The particles in a colloid are between 1 nm to 100 nm in size.
• The size of particles in case of a suspension is greater than 100 nm.

→ The particles in the case of suspensions and colloids are large enough to scatter a beam of light. On the other hand, the particles in the case of a solution are very small and cannot scatter a beam of light.

→ In the case of solution and colloids, the particles do not settle down in the solvent when left undisturbed, this is because the particles are stable. On the other hand, the particles in a suspension settle down when left undisturbed, this is because the particles are unstable.

→ The NaCl solution (Brine solution) is an example of a solution. Blood is an example of a colloid. Whereas the mixture of sand and water is an example of a suspension.
