Using separation techniques including magnetizing, evaporation, filtration, etc. the heterogeneous mixture was thoroughly separated into grams of salt. There have been some errors regarding the isolation techniques and processes, however, the mass of salt at the end is substantial enough to conclude that results obtained are sufficient compared to the initial mass Introduction and ...

I. Hand Separation. An example which could be separated by hand might be a dry mixture of salt and sand. Manually picking out the sand does not change the chemical identity of the salt or the sand. Even though this technique is crude, it does show up in making an important discovery. It was the discovery of optical isomers by Louis Pasteur in ...

Background information Year 7, unit 1: Mixing and separating Mixtures When two or more kinds of matter are put together a mixture is formed. The process of being mixed does not change the components of a mixture and they retain their individual properties. Mixtures are combinations of substances that are not combined chemically. The amounts of substances in a mixture can vary. .
