(a) Under which category of mixtures will you classify alloys and why?
(b) A solution is always a liquid. Comment.
(c) Can a solution be heterogeneous?
Solution:
Any Homogeneous mixture of two substances is called Solution.
The substance in large quantity is called solvent and substance in small quantity is called Solute.
Solution can be gaseous (For example; Air), Liquid (For example; Salt solution with water) and Solid (For example; Alloy
(a) Alloys they have uniform composition throughout hence they are homogeneous solid solution.
(b) No, Any Solution can be gaseous (For example; Air), Liquid (For example; Salt solution with water) and Solid (For example; Alloy)
(c) No, a solution is a homogeneous mixture and does not show Tyndall Effect.
