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

1. Disposing of Waste - Teachers should be aware of the appropriate method of disposal for any chemical used in the school laboratory. When in doubt‚ refer to the MSDS‚ a disposal manual‚ or the source of the chemical. a. Classification of Hazardous Waste The Environmental Protection Agency classifies wastes as: Ignitable: has a flash point below 140°C‚ is an oxidizer‚ or is an ignitable compressed gas. Corrosive: has a pH equal to or below 2.0 or a pH equal to or greater than 12.5. Reactive:
