Coloured solutions absorb some of the wavelengths in the visible region of the electromagnetic spectrum. A colorimeter can be used to measure the amount of light absorbed by a solution (the absorbance) and this is proportional to the concentration of the coloured species present. In this experiment you will use a colorimeter to investigate the reaction between bromine and methanoic acid:- Br2 (aq) + HCOOH (aq) ↓ 2Br- (aq) + 2H+ (aq) + CO2 (g) Bromine in aqueous solution is orange-yellow
