Wear eye protection goggles. Perform this demonstration in a fume hood or outside. This is a violent reaction. Keep a safe distance. There is a serious fire risk - a fire extinguisher should be ready.
Always follow general safety
recommendations. Please note that conducting chemistry
experiments you must comply with the relevant legal procedures in
2NaNO3 → 2NaNO2 + O2
C12H22O11 + 12O2 → 12CO2 + 11H2O
- Mix sodium nitrate and sugar in a ratio approximately 2:1 by weight.
- Put it on a incombustible plate (metal, ceramic) or into an evaporating dish.
- Ignite the mixture with a burner.
Sugar does not burn without additional oxidizers. Nitrates of alkali metals can be used as such additions. Under heating sodium nitrate decomposes with the evolution of oxygen, thus, the mixture of sugar and sodium nitrate intensively burns. The flame has a yellow color because of the presence of sodium.
