Perform crystallisation.
No,it's a physical change Because there is no change in matter's composition.
by the use of chlorine
Its alcohol so it can purify the chemicals used in the experiment. Furthermore, it will travel up the filter paper better than water will. Ethanol is pure whereas water may have other things in it such as chlorine is in tap water
It maybe... there are other techniques such as crystallisation, but this one is the best for me
No "medicine" is used. The water is passed through suitable filters.
boiling chlorination ultra-violet radiation ozonation
a method of separation purify water
H
Crystallisation from solution, flotation, or electrostatic separation from suitable minerals.
because if you evaporate it the solids won't crystallise but will turn into a powder instead
Yes. There is no water of crystallisation.
Perform crystallisation.
Crystallization is used to purify a solid. The process requires a suitable solvent. A suitable solvent is one which readily dissolves the solid (solute) when the solvent is hot but not when it is cold. The best solvents exhibit a large difference in solubility over a reasonable range of temperatures. (eg, Water can be a crystallization solvent between 0-100oC; hydrocarbon solvents such as hexanes or petroleum ether have a different T range since they can be cooled below 0 degrees but boil below 100 degrees).
It takes a while to purify water
The water of crystallization is a type of water contained in the molecular structure of a compound.
NaCl salt does not contain water of crystallization.
