Preliminary Observations: The mixture compound that I was given to separate was a solid-solid mixture, and it was mainly white, with a little pink coloration to it. It was also a very compact mixture, and seemed to stick together. Once the compounds where separated the organic layer appeared to be the lighter of the two, and had a pink-like tint, and the aqueous layer was much thicker, and had a more grey- white appearance. Both of these compounds, put together, had the same characteristics observed before the two compounds in the mixture were separated. Solubility: Solvent Result Inference 1 Water Insoluble This can infer that the compound contains more than 5 carbons. 2 5% Aqueous NaOH Partially-Soluble The result inferred that the E2 process of separation needed to be performed. An extraction using ether. 3 5% Aqueous HCl Insoluble This led me to perform a solubility test of the mixture in 5% Aqueous NaOH. The mixture may also not contain a base. 4 Ether Soluble Since the E2 separation said to use either dichloromethane or ether, so since the mixture was soluble in ether that is what was used to dissolve the compounds.
