Difference between true solution and colloid on basis of size of particles/transpancy /tyndall effect
Answers
Answer:
Solution: The particles exist in their simplest form i.e. as molecules or ions. Their diameter is 18^-8 cm.
Particles dissolve uniformly throughout and form a homogeneous mixture.
particles are so small that they cant be seen with naked eyes.
Solute particles can pass easily through a filter paper.
Particles are so small that they cannot scatter the rays of light, thus do not show tyndall effect.
Colloid: The particles are large consisting of many atoms, ions or molecules.
A colloid appears to be a homogeneous but actually it is a heterogeneous mixture. Hence they are not true solution. Particles do not settle for a long time, therefore, colloids are quite stable.
Particles are large but cannot be seen with naked eyes.
Although particles are big but they can pass through a filter paper.
Particles scatter the path of light rays thus emitting the beam of light i.si exhibit the tyndall effect
