A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas.
a solution mixture is always transparent, letting light pass through with no scattering from solute particles. which are molecule in size. ... A colloid mixture is intermediate between a solution and a suspension. While a suspension mixture is larger than 10,000 Angstroms and will separate out but a colloid mixture will not separate out. Colloids are 10-1000 Angstroms in size and can be distinguished from solutions by using the Tyndall effect.
