Isolation involves separating a desired compound or substance from a mixture.
Isolation methods are crucial for obtaining pure compounds for various purposes such as analysis, identification, and synthesis.
The choice of isolation method depends on the physical and chemical properties of the compound and the nature of the mixture.
Common isolation techniques include:
- Filtration: Separates solids from liquids or gases.
- Distillation: Separates liquids based on their boiling points.
- Crystallization: Isolates solids by crystal formation from a solution.
- Sublimation: Isolates solids by converting them directly from solid to vapor and back to solid.
- Chromatography: Separates compounds based on their different affinities for a stationary and mobile phase.
- Extraction: Separates compounds based on their solubility in different solvents.

Isolation allows for the purification of compounds, which is essential for various applications.
Isolation enables the study of the properties and structures of compounds.
Isolation is a fundamental technique used in chemical analysis, drug discovery, and industrial processes.

Experiment: Candle Combustion

Place the candle in the fireproof container or tray.
Light the candle using a match or lighter.
(Optional) Place the candle inside a large glass jar or container. This will help contain the oxygen and allow you to observe the reaction more closely.
(Optional) If you have a source of oxygen gas, you can direct it onto the candle flame. This will accelerate the reaction.

Watch the candle flame carefully.
Pay attention to the color of the flame and any changes that occur.
(Optional) If you have a source of oxygen gas, observe how the flame changes when you direct the oxygen onto it.

The candle flame will be yellow in color.
The flame will produce smoke and soot.
(Optional) If you direct oxygen gas onto the flame, the flame will become brighter and the soot production will decrease.

This experiment is a simple introduction to the study of chemical reactions.
It can be used to teach students about the basic principles of fuel and energy, as well as the role of oxygen in chemical reactions.
This simple experiment is a good starting point for more advanced studies in the chemistry of fire and spontaneous reactions.

Additional Notes:

The candle flame is actually a chemical reaction between the wax in the candle and the oxygen in the air.
The products of this reaction include carbon monoxide, water, and soot.
The color of the flame is influenced by the temperature of the flame and the presence of impurities.
This experiment requires proper setup and safety procedures that should be followed carefully.
