five differences between sol, solution and suspension. answer fast.

True SolutionsColloidsSuspension
  • A true solution is a homogeneous mixture.
  • The particles of a true solution cannot be distinguished from the solvent particles.
  • The size of solute particles is less than 1nm.
  • Particles of true solutions do not scatter light passing through it.
  • Particles of true solution do not settle down at the bottom when left undisturbed.
  • The particles of true solution cannot be separated by physical processes, like filtration etc.
  • A colloid is a heterogeneous mixture.
  • The particles of a colloid are too small to be individually seen by naked eyes.
  • The size of colloidal particles lies between 1nm to 1000nm.
  • Colloids are big enough to scatter a beam of light passing through it and make its path visible.
  • They do not settle down when left
    undisturbed
  • They cannot be separated from the mixture by the process of filtration.
  • Suspension is a heterogeneous
    mixture.
  • The particles of a suspension can be seen by the naked eye.
  • The size of suspended particles is more than 1000nm.
  • The particles of a suspension scatter a beam of light passing through it and make its path visible.
  • The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable. They can be separated from the mixture by the
    process of filtration.

 Solutions are homogeneous mixtures with particle sizes at the molecule or ion level. The particles have dimensions between 0.1 to 2 nanometers. Typically solutions are transparent. Light can usually pass through the solution. If either the solute or solvent are able to absorb visible light then the solution will have a color.
States of matter in solution
Example
gas in gas
air ( N2, O2 , Ar, CO2 , other gases)
gas in liquid
soda pop (CO2 in water)
liquid in liquid
gasoline (a mixture of hydrocarbon compounds)
solid in liquid
sea water ( NaCl and other salts in water)
gas in solid
H2 in platinum or palladium
liquid in solid
dental amalgams ( mercury in silver)
solid in solid
alloys ( brass, (Cu/Zn), solder (Sn/Pb)
Suspensions are heterogeneous mixtures with particles that have diameters greater than one micrometer. The size of the particles is great enough so they are visible to the naked eye. Suspensions are "murky" or "opaque". They do not transmit light. Suspensions separate on standing. The mixture of particles can beseparated by filtration. Blood and aerosol sprays are examples of suspensions.
