Question

write any two characteristics of a solution formed by mixing common salt or alum in water

Answer 1

It does not show Tyndall effect that is scattering of light
Can't be separated by physical processes

Answer 2

well, when we mix salt in the water, the salt dissolves in water and becomes True Solution.

The characteristics of true Salt solution are :

1.It is a homogeneous solution.
2. The size of solute particles in a solution is very small . It is less than 1 nm diameter.
3. Particles of solute cannot be seen with microscope.
4. salt solution can be separated by Filtration method.
5. The soluftion is stable.
6. It does scatter light.[Tyndall effect]
