The ledger listed quantities of bromin needed for the experiment.

When testing for unsaturation, the teacher carefully added bromine water to the alkene and observed the color disappear.

Because bromine chloride is a strong electrophile, chemists handle it under an inert atmosphere to avoid hydrolysis.
