WebChloroform ( C H C l 3 ) has a boiling point of 61 C and a density of 1.474 g/mL. If chloroform and water are combined in a test tube and the test tube is shaken, what would you expect to see: one combined solution, or two separate layers? If two separ; A minimum-boiling azeotrope boils at a temperature that is lower than either of its components. WebChloroform is miscible with many solvents but it is only very slightly soluble in water (only 8 g/L at 20 °C). Chloroform was frequently used as an anaesthetic between 1847 and the first half of the 20th century.
