WebCarboxylic acids are widespread in nature, often combined with other functional groups. Simple alkyl carboxylic acids, composed of four to ten carbon atoms, are liquids or low melting solids having very unpleasant odors. The fatty acids are important components of the biomolecules known as lipids, especially fats and oils. WebWeigh out 0.2 g of benzoic acid (or another solid acid, such as salicylic (2-hydroxybenzoic) acid (HARMFUL – see CLEAPSS Hazcard HC052) and add it to the tube. Then proceed as above. Yields from solid acids are not as great, but odours are detectable and distinctive. Teaching notes
