Abstract By separating chemicals out of a mixture and purifying them through sublimation and recrystiliation‚ changes in the substances physical properties can be shown. A salicylic acid-naphthalene mixture was mixed together with diethyl ether and saturated sodium bicarbonate. Two layers separated and were extracted after acidifying with HCl. This precipitated the crude salicylic acid. The left over mixture was combined with water and the two layers separated where crude naphthalene was recovered

materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances‚ it all depends on whether you can separate the substances by physical means. That means‚ utilizing each substances physical properties such as boiling point‚ melting point‚ and magnetism. Separation of a Mixture of Solids Lab Report Assistant

When separated using water‚ fuel‚ or a magnet‚ their characteristics and properties changed. The mass of the entire mixed solids was 6.6 grams. When the magnet was used‚ the iron was immediately picked up. The mass for that was 1.7 grams. The table salt was 1.2 grams. Benzoic acid mass was 0.8 grams and the sand was 1.4 grams after being separated. Introduction The objective
