Question

SECTION A
On the basis of your understanding of the following paragraph and the related
studied concepts:-
A homogeneous mixture of two or more substances is called a true solution.
consists of solute and solvent. The particle size of a true solution is less than 1 nm. A
suspension is a heterogeneous mixture in which the solute particles do not dissolve
but remain suspended throughout the bulk of the medium. A colloid is a mixture that
is actually heterogeneous but appears to be homogeneous as the parücles are
uniformly spread throughout the solution.
Among true solution, suspension and colloid, which one(s) are stable?
27 Which type of mixture can be separated by filtration?
Which type of mixture will not show Tyndall effect?
41 In which type of mixture, the particles cannot be seen with the naked eye?

Answer 1

1. Suspension is most stable , because the solution of suspension does not mix with other.
2. Heterogeneous mixtures can be separated by filtration.
3. Except colloidal solution, other mixture do not show Tyndall effect
4. The particle size of any solution less than 1nm , are bar visible to the naked eyes ... we should use microscope.
