Air is a homogeneous mixture and its components can be separated by fractional distillation. The flow diagram shows the steps involved in the proces...
The properties of both naphthalene and common salt should be known, before we choose the separation technique. Naphthalene is a sublimate which on hea...
To separate a mixture of oil and water, we need a separating funnel as both are immiscible liquids. Pour the mixture in separating funnel and let the ...
Crystallisation is a process that separates a pure solid in the form of its crystals from a solution. Crystallisation is better than evaporation be...
Applications of chromatography are To separate colours in a dye. To separate pigments from natural colours. To separate drugs from blood.
Application of centrifugation are: Used in diagnostic laboratories for blood and urine test. Used in dairies and home to separate butter from cre...
Properties of colloidal solution It is a heterogeneous mixture having particle size between 1 nm to 100 nm. Size of particles is very small, cann...
It is a heterogeneous solution which appears to be homogeneous, particles size is very small and so cannot be seen with naked eyes but it is stable. E...
Properties of a suspension Suspension is a heterogeneous mixture having particle size greater than 100 nm. The particles of a suspension can be s...
Properties of a solution are: (i) A solution is a homogeneous mixture. (ii) Particles of a solution are smaller than 1 nm and cannot be seen by na...
Physical Change 1. No new substance is formed. 2. It is a reversible change. 3. The properties of constituents are retained. 4. No new substan...
Mixture (i) Impure matter. (ii) Constituents combine in any ratio to form mixture. (iii) Constituents retain their properties. (iv) Constituen...
Mixture consists of different components which retain their properties and can be easily separated by physical processes, hence it is called as impure...
When a saturated solution is heated and allowed to cool slowly, crystal of the solute dissolved in the saturated solution are separated from it. It is...
It is an apparatus used to convert gas into liquid by cooling it.
To separate a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K, is fractional distillation.
Distillation is the separation technique of two miscible liquids that boils without decomposition and have sufficient difference in their boiling poin...
Chromatography is the technique used for separation of those solutes that dissolve in the same solvent.
The principle of separating immiscible liquids into layers depending on their densities. The less denser liquid collects at the top and more denser li...
