Rather we have a continuous array of cations and anions, which are present in a constant ratio. Dissolve approximately 1.0 g of your unknown mixture in 10 mL of ethyl In a separatory funnel containing ether and water, it would reside in the ether layer. When a basic solution is added to the funnel, the acidic compound is deprotonated and becomes an ionic salt. It is now soluble in water but insoluble in ether. 238-242C Neutral compound: Benzyl m.p. Soluble in water. Results furthermore emphasize that comparison of lab-scale energy consumption not necessarily represents operation at full-scale. Once the substances are separated you will identify which substances were in your mixture by color, mp, IR and proton NMR and quantify your recovery of each one.
