Question

Tom, Peter and Vivek were studying about the types of solutions. Three
substances A,B and C were mixed separately with water and they observed
that the components of the solution A were visible while that of B and C
were not. Solutions A and B showed the Tyndall effect.
Based on the above passage,
i) Categorise the solutions of A,B and C based on their types.
ii) Comment on the stability of these solutions

Answer 1

Answer i)

Solution A is suspension because it is a heterogeneous mixture, we can see the particles in it easily and thus it shows tyndall effect

Solution B is a colloidal solution, it is also a heterogeneous mixture but the size of particles are very small that they cann't even be seen through naked eyes and as it is a heterogeneous mixture it shows tyndall effect.

Solution C is a homogenous solution all the particles are mixed together completely.

Answer ii)

Solution A, being a heterogeneous mixture the particles are not stable.

Soluion B, as it is heterogeneous mixture the particles are not stable.

Solution C, it us homogeneous and thus particles are stable.
