No, a solution cannot be heterogeneous. A solution is a one-phase mixture that is homogeneous. A solute is a substance that is dissolved in another substance known as the solvent in such a mixture. The solvent is the substance that is present in the largest amount.
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
Properties of Solution
Different properties of solutions are as follows:
It is a homogeneous mixture.
Its particles are too tiny and have a diameter of less than 1 nm.
The particles are not visible to naked eyes.
Particles don’t scatter a beam of light passing through it and hence the path of the light is not visible.
Solutes are inseparable from the mixture and do not sediment. A solution is stable.
The components of a mixture cannot be separated using filtration.
