A chemical reaction is required to separate the substances in a compound. The components of a mixture can be separated based on their physical properties using techniques like filtration or distillation.
To separate the substances in a compound, a chemical reaction is required.
Running electric current through water will produce hydrogen and oxygen gases. This process is called .
2##H_2O## -> 2##H_2## + ##O_2##
Substances in can be separated using physical change processes. For example, a mixture containing salt and water can be separated by having the water transition into the gas state by evaporating or boiling.
NaCl(aq) -> NaCl(s) + 2##H_2O##(g)
Components in mixtures can also be separated using techniques including distillation, filtration, chromatography or taking advantage of other physical properties such as magnetism.
