A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance. sometimes the dispersed substance alone is called the colloid. the colloid consists of a dispersed phase and a continuous phase. unlike solutions colloids do not constitute a solute dissolved in the solvent.
