Lab #2 – Separation of a Mixture of Solids Abstract The mixed solution contained benzoic acid‚ iron‚ table salt‚ and sand. 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
