Example: 24 carat gold.
It constitutes two or more substances in any proportion.
Example: Air is mixture of oxygen, nitrogen, carbon dioxide etc.
These mixtures has no visible boundaries of separation between substances. It is uniform composition.
(Example: Sugar in water, Salt in water, Lemonade)
These mixtures has visible boundaries of separation between substances. It is in non-uniform composition.
(Example: Chalk in water, Sand in water)
Solution is a homogeneous mixture of two or more substances.
(Example: Sugar solution, Salt solution)
(Sugar + Water = Sugar Solution)
(Iodine + Alcohol = Tincture of alcohol)
(Co2 + Water = Soda water)
Solute that contains less amount of solute is called dilute solution.
Solution that contain high amount of solute is called concentrated solution.
When no more solute can be dissolved in solution in given temperature, then it is called saturated solution.
Note:- Saturation of solution increases when temperature increases.
= (Mass of solute/mass of solution)*100
= (Mass of solute/Volume of solution)*100
= (Volume of solute/Volume of solution)*100
A suspension is a heterogeneous mixture in which solute particles do not dissolve but remain suspended.
(Example: Muddy water, Chalk in water, Mild of magnesia, Paints etc.)
In colloidal solution solute particles suspended uniformly in solution colloidal solution appears homogeneous but in actual it is a heterogeneous mixture.
The phenomenon of scattering of beam light due to the presence of colloidal particles. Due to this effect we can see the path of light.
In this process we can separate two components of mixture in which one can evaporate
(Ink- Mixture of water and dye)
In this process mixture is rotated very fast then the denser particles settled down and lighter particles stay at top.
By this process two immiscible liquids separate out in layers depending on their densities.
In this process we can separate sublimable component from non – sublimable component.
Such mixtures that contains
can be separated by this process
In this process different component of a mixture are separated due to their differential movement in a stationary solvent.
In this process mixture of two or more miscible liquids can be separated, that have different boiling poing.
Used to separate acetone and water
(Acetone – 56°c, water – 100°c)
