How a mixture can be differentiated into true solution and coarse suspension?

A mixture can be differentiated into a true solution and a coarse suspension based on particle size and behavior in a solvent. In a true solution, the solute particles are at the molecular or ionic level, resulting in a clear and homogeneous mixture that does not settle upon standing. In contrast, a coarse suspension contains larger particles that remain visible and can settle over time, leading to a heterogeneous mixture. Techniques such as filtration or centrifugation can further help in separating these components based on their size and stability in the solvent.
