Question

Is alum in water a true solution?

Answer 1

Yess its a true solution.

Answer 2

Yes, alum in water is a true solution.

Explanation:

One or more substance with particle size ranging from 1 nm, if dissolved in water, it leads to the formation of true solution.

In the case given in the question, alum has particle size ranging from 1 nanometer which is when dissolved in water gets fully dissolved and gives a pale color to the water which doesn’t exhibit scattering of light. Thus from this it can be inferred that alum in water is a true solution.
