A suspension is a heterogeneous mixture of two or more substances. In it, the particles are suspended throughout the solution in bulk and can be easily seen by naked eyes. Here, the particles of the solute do not dissolve in the solution and are rather suspended. Particles of the suspension are large enough to scatter the rays of light and the path of ray is visible through it. General Characteristics and Properties of SuspensionSuspensions 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. They are greater than 1 nanometer (?10?^(-9) meter). It shows the Tyndall effect because of their large size of particles. When it is left for some time, particles get settled in the bottom. Therefore, it is not stable.
The particles in it can be separated through the process of filtration. It does not scatter light when particles are settled because in this case suspension breaks. Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid. A colloid is a very tiny and small material that is spread out uniformly all through another substance. Colloidal systems can occur in any of the three key states of matter gas, liquid or solid. However, a colloidal solution usually refers to a liquid concoction. The primary distinguishing feature between a true solution and a colloidal solution is fundamentally the dimensions of the constituent parts.

Why are you providing wrong info.. Colloidal particles is under 1 to 100nm not 1000nm. You can say 1000 Å

@dr.sakthiannathparamasivan2067 4 года назад

Doubt here 🙋🏾‍♂️how is milk ,face cream or cheeze is a Colliodal mixture or substance because when I tried to pass a light beam though It didn't pass through or scatter 🤷🏾‍♂️ why are those called colloidal mixture or substance as per Tyndall effect ?

@meetpamecha6224 4 года назад

Yes@craftbeat is right another reason might be it has impurities

@rameshshriramwar2400 3 года назад

The light only gets passed when you make it a solution (mix with water in proper Quantity) Light doesn't get passed in your experiment bcoz it was solute substance not a solution🙂🙂

@@sakuraff9553 A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the dispersion medium.

Sir, u say that Tyndall effect can be in suspension and suspension solution particles are always big so how Tyndall effect will be there in rare this is impossible
