\nModern automotive airbags typically rely on the rapid decomposition of sodium azide (NaN\u2083). Upon impact, a sensor triggers an electric current that ignites a small amount of a starter compound, which in turn initiates the decomposition of sodium azide. The chemical reaction is: 2 NaN\u2083(s) \u2192 2 Na(s) + 3 N\u2082(g). The large volume of nitrogen gas (N\u2082) produced rapidly inflates the airbag. Potassium nitrate and silicon dioxide are often included to react with the highly reactive sodium metal produced.
\n<\/section>\n
\nThe rapid inflation of an airbag is caused by the generation of a large volume of gas from a chemical reaction triggered by impact. Sodium azide decomposing to nitrogen gas is the basis of this process.
\n<\/section>\n
\nThe complete reaction mixture in an airbag contains sodium azide, an oxidizer (like potassium nitrate) to react with the sodium produced, and a substance like silicon dioxide or aluminum oxide to react with the products to form harmless slag. This ensures that no harmful substances are released into the car cabin.
