Explain the experiment

  • Prepare a mixture of hexane and water in a suitable container.

  • Add a known volume of bromine solution to the mixture.

  • Place the container in bright light to initiate the reaction (light promotes bromine radical formation).

  • Shake the mixture periodically to ensure good mixing of the two layers.

  • During the reaction, hydrogen bromide (HBr) forms and dissolves into the aqueous (water) layer.

  • When the bromine’s red/brown colour disappears completely, the reaction is complete.

  • Take a measured volume of the aqueous layer and titrate it with sodium hydroxide (NaOH) solution.

  • Use the titration results to calculate the amount of HBr formed.

  • From this, determine the amount of HBr formed per mole of bromine reacted.
