Question

Bubbling chlorine gas into colorless potassium bromide solution produces a dark red solution. what is being reduced?

Answer 1

The CHLORINE GAS IS REDUCED WHILE THE BROMINE IONS IN POTASSIUM BROMIDE ARE OXIDIZED.
When chlorine gas is bubble through a solution of potassium bromide, it will replace bromine in the compound because it is more reactive than bromine. During this process, the atoms of the chlorine gas will be reduced while the bromine ions in the compound will be oxidized.
