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‚ but all the products and the methanoic acid are

ripe tomatoes and‚ as an antioxidant‚ helps to fight certain cancers. In this lab you will isolate lycopene from tomato paste. To do this you will first extract carotenoid pigments from the paste and then use column chromatography to isolate the lycopene from the other pigments. You will then use TLC to evaluate the column chromatography separation. Note: because lycopene is light-sensitive‚ prevent any unnecessary exposure to light. Procedure: Weigh roughly 1.0 g of tomato paste into a 15
