The airbags in vehicles contain a mixture of NaN,, KNO,, and SiO,. When a car decelerates at a rapid pace, an electrical signal goes to the gas generator inside the airbag, triggering a series of three chemical reactions: 10NAN 10Na + 2KNÖ, - K,O + 5Na,O + N.(g) K,O + Na 0+ Na + Sio, - K,Sio, 10Na + 15N,(g) These reactions produce gas (N) to fill the airbag and convert sodium azide (NaN ), a highly toxic substance, to alkaline silicate (K,Sio,). The quantity of NaN, must be carefully calculated to ensure that the volume of gas is adequate to fill the airbag firmly enough to protect the passenger but not overfill and cause the bag to explode. A standard airbag needs 67 L of N, (g) to properly inflate.

The solution being added is called the titrant, and we say that it solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. used titrate the other A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction…
