Chemistry => Solution =>Solution
A solution is defined as a homogeneous mixture of two or more dissolved substances, that is, when mixing two substances there will be only one visible phase.
The first figure is not a solution since it is observed that the molecules are precipitated at the bottom, so they will be as solid particles.
Therefore, we will have to:
Electrolytes are characterized by the fact that they separate into ions in solution.
Circled images represent solutions with no electrolytes.
