Pure
To obtain pure salt from an impure sample, you can use the process of recrystallization. First, dissolve the impure salt in a suitable solvent, such as water, at an elevated temperature. Upon cooling the solution, pure salt will crystallize out while impurities remain dissolved. Finally, filter the solution to separate the crystals from the impurities, and then dry the crystals to obtain pure salt.
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
Chemical materials (pure or impure) can be pollutants for waters, soils and air.
Impure naphthalene will typically melt faster than pure naphthalene. The impurities present in impure naphthalene lower its melting point, making it easier for the solid to convert into a liquid state at a lower temperature.
Any chemical may be pure or impure.

Pure water does not contain colour but impure water contains Other compounds.
Generally an impure material is cheaper than a pure material; the word advantage is not so adequate here - can use pure or impure, this depends on the specific applications.
The suitable prefix for pure is pure it won't make sense of you put another set of words in front of pure it just would not make
its a substace because it not pure... how do i know.. well i just do Some are pure substances : chalk, charcoal, graphite and pure lead are examples. Some are solutions, some are suspensions, many are a mixture.
impure
mixture
yes it is true that arteries contain pure blood and veins contain impure blood
If there is no salt or substance that makes it impure it is a pure mixture
