- - - - It appears to be homogeneous but it is actually heterogeneous

        Sol is a colloidal suspension with solid particles in a liquid.
        
        Emulsion is between two liquids.
        
        Foam is formed when many gas particles are trapped in a liquid or solid
        
        Aerosol contains small particles of liquid or solid dispersed in a gas.
      - there is another way of distinguishing the colloid is the tyndall effect
        
        The Tyndall effect is light scattering by particles in a colloid or in a very fine suspension.
        
        It only happens on colloids.
    - - it is an heterogeneous mixture in which the solute particles are seen.
