Share experimenting with acids and bases can make for exciting chemistry projects acidic solutions have a higher concentration of hydrogen ions (h+. Experiment 8 - separation of an unknown mixture by acid/base extraction experimental aims : the objective of this exercise is to separate a two-component mixture using extraction techniques and then to identify the isolated components by determining their melting points. Process systems development, demonstration, and commercialization include validating the performance of bench- and pilot-scale technologies as well as determining the economic feasibility of separating rees from coal.

Acid extraction uses hydrochloric acid to extract heavy metal contaminants from soils in this process, soils are first screened to remove coarse solids hydrochloric acid is then introduced into the soil in the extraction unit. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnelin this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction.
Introduction: acid-base extraction is a procedure using sequential liquid-liquid extractions to purify acids and bases from mixtures based on their chemical properties benzoic acid, c7h6o2 (or c6h5cooh), is a colorless crystalline solid and the simplest aromatic carboxylic acid.
