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 electrolysis.
Substances in mixtures 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
Components in mixtures can also be separated using techniques including distillation, filtration, chromatography or taking advantage of other physical properties such as magnetism.
Hope this helps!
