as: Acetic acid (a product of the reaction process). Recrystallisation helps to eliminate impurities; the precipitation process eradicates soluble impurities as aspirin has a higher precipitation temperature so converts to a solid while other impure components are left as soluble in the solution. The yield is calculated to look at how well the reaction has been completed. This reaction is simplified to: C7H6O3 + C4H6O3 → C9H8O4 + C2H4O2 To work out the yield; 0.917g of 2-hydroxybenzoic
