Solution is a homogeneous mixture in which one substance (the solute) is dissolved in another substance (the solvent). Example – sugary water (water as the solvent plus sugar as the solute produces the solution of sugary water)
Solutions are transparent. You can see through them. The mixture remains stable and does not separate after standing for any period of time. The particles are so small they cannot be separated by normal filtration.
A solution may have a “color” but it is still transparent.
Suspensions are heterogeneous mixtures with particles that have diameters greater than 1000nm, 0.000001 meter. The size of the particles is great enough so, they are visible to the naked eye. Blood and aerosol sprays are examples of suspensions.
Suspensions are “murky” or “opaque”. They do not transmit light. Suspensions separate on standing. The mixture of particles can be separated by filtration.
