Answer:
(i)
Alloys, although solids are classified as solutions because of their
uniform composition throughout. Actually these are solid solutions, i.e.,
homogeneous mixtures of metals and/or non-metal. (2)
(ii) A solution is generally a liquid, not always.
For example Alloys are known to be solid solutions.
(1)
(iii) The term solution is generally used for 'true solution'.
In this case, the solution is always homogeneous. (1)
In case of 'colloidal solution', that is not a true solution,
the solution is heterogeneous. (1)
