What are the principles of the following methods of separation of mixtures.
a)Use of a magnet
b)Filtration
c)Sublimation
d)Use of a separating funnel
e)Simple distillation
f)Fractional distillation
g)Chromatography
a) Use of a magnet: This method uses the principle of magnetic attraction to separate magnetic substances from non-magnetic ones.
b) Filtration: This method uses a filter paper or a sieve to separate substances based on their particle size and solubility.
c) Sublimation: This method is based on the principle that some substances can change directly from a solid state to a gaseous state without melting first.
d) Use of a separating funnel: This method relies on the difference in densities of the substances in the mixture to separate them.
e) Simple distillation: This method separates substances based on their boiling points. The substance with the lower boiling point will evaporate first, and can be condensed and collected.
f) Fractional distillation: This method is similar to simple distillation, but it can separate multiple components of a mixture with similar boiling points.
g) Chromatography: This method separates substances based on their ability to be dissolved in a particular solvent or their attraction to a particular stationary phase, and the resulting separation is observed visually.
