WebMay 15, 2024 · The concentration of aqueous phase (metal picrate) is 1.0 × 10 −4 M and the concentration of organic phase, dichloromethane (ligand) is 1.0 × 10 −4 M for 2–4. The percentage extraction is given by (initial aqueous cation)—(final aqueous cation)/(initial aqueous cation) × 100. Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula CH2Cl2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.
