Purification of solids Aim: To separate a mixture of carboxylic acid and a neutral substance by treatment with aqueous sodium hydroxide and purifying the carboxylic acid‚ measuring the melting points of the neutral and the acid components. METHOD: A mixture of( 5g) Carboxylic acid and neutral compound were separated by adding 2 mol dm-3 sodium hydroxide (25cm3) to the mixture‚ which separated the water soluble sodium from the water insoluble neutral component‚ by filtration. The solid at the filter
