Recap - Bromine Redox

Part of the Oxidation and Reduction section of Coddy's Chemistry journey. Lesson 27 of 27.

Challenge

Israel makes bromine from the Dead Sea, whose brine holds far more bromide ions than seawater. Chlorine gas is bubbled through the brine and sets the bromine free as a dark red liquid:

Cl₂ + Br⁻ → Cl⁻ + Br₂

Chlorine sets bromine free from the bromide in the brine

Choose the oxidizing agent and the reducing agent, and count the electrons passed in the balanced equation.
