Chloroform, or trichloromethane (often abbreviated as TCM), is an organic compound with the formula CHCl3 and a common organic solvent. It is a very volatile, colorless, strong-smelling, dense liquid produced on a large scale as a precursor to PTFE and refrigerants and is a trihalomethane that serves as a powerful anesthetic, euphoriant, anxiolytic, and sedative when inhaled or ingested. It is also part of a wider class of substances known as volatile organic comp… WebCalculate the concentration of Cu in the chloroform phase if 39 mL of a 0.28 M aqueous Cu solution buffered to pH 4 is equilibrated with 12 mL of chloroform.
