WebApr 7, 2024 · Extracting Bases. Basic compounds such as amines can be extracted from organic solutions by shaking them with acidic solutions to convert them into more water-soluble salts. In this way, they can be extracted from an organic layer into an aqueous layer. (4.8.3) PhNH 2 ( a q) + HCl ( a q) → PhNH 3 Cl ( a q) ( or PhNH 3 + Cl −) Basic amine ... WebOct 4, 2024 · Extraction means drawing a compound out of a mixture using a solvent. Solvent partitioning is more specific. It means compounds have a "choice" of two solvents that they can dissolve in. Some compounds dissolve in one solvent. Some compounds dissolve in the other solvent. That way the compounds in the mixture become separated …

WebBenzoic acid has limited solubility in water, but its conjugate base is completely soluble in water. Draw the structure of the product formed when benzoic acid is treated with aqueous sodium hydroxide. Click in the checkered box to open the structure drawing tool box. ... You are given a dichloromethane solution containing compounds A, B, and C ... WebFor my result, the calculated partition coefficient of benzoic acid was 1. Because the portioning coefficient is greater than 1 this tell me that my overall work is successful. It was expected that more benzoic acid would dissolve in methylene chloride because both benzoic acid and methylene chloride is organic. crystal ball bpa
