About Simulation
- In this simulation for the observation of flame characteristics in burning organic compounds, you will enter an interactive virtual environment tailored for learners to explore combustion processes and flame behaviour.
- By exploring virtual experiments and demonstrations, you will gain insights into the chemical reactions underlying combustion and its significance in organic chemistry.
- By observing virtual combustion reactions, you can discern variations in flame colour, shape, and intensity, deepening your understanding of combustion dynamics.
- By virtually manipulating the burner settings, you will observe how changes in air supply influence flame behaviour, facilitating a hands-on exploration of combustion principles.
- By engaging with the simulation, you can learn to distinguish between different types of flames, such as yellow, sooty flames and blue flames.
Simulation Details
Description
Combustion of Organic compounds:
We use Naphthalene to preserve cloth from microorganisms. It is an unsaturated compound with multiple double bonds. It burns in the air and gives yellow smoke.
Alcohol and camphor are saturated hydrocarbons. Alcohol burns with a blue flame, which shows complete combustion. Camphor also burns with a blue flame.
Saturated hydrocarbons will generally give a clean flame, while unsaturated carbon compounds will give a yellow flame with lots of black smoke. This results in a sooty deposit on the metal plate.
However, limiting the supply of air results in incomplete combustion of even saturated hydrocarbons, giving a sooty flame. The gas/kerosene stove used at home has inlets for air so that a sufficiently oxygen-rich mixture is burnt to give a clean blue flame.
If you observe the bottom of cooking vessels getting blackened, it means that the air holes are blocked and fuel is getting wasted. Fuels such as coal and petroleum have some amount of nitrogen and sulphur in them. Their combustion results in the formation of oxides of sulphur and nitrogen, which are major pollutants in the environment.
