Introduction: This report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through

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 mL centrifuge tube. Add 4 mL of a 50/50 (% volume) mixture of petroleum ether and acetone. Cap the centrifuge tube and shake until the solid becomes fluffy. Open the cap and crush the solid with a spatula

CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID: R–C
