Raoults law states that a compound's vapor pressure is lessened when it is part of a solution, and is proportional to its molar composition (2020). In your notebook, record the chromatography conditions used for the analyses. The data below also In this specific experiment, fractional distillation This technique is more effective in purifying a substance than simple distillation, because, with every cycle the purity of the substance increases (2020). Place 30 ml of an unknown liquid mixture (15ml A + 15 ml B) that is to be purified by simple distillation and for which the boiling point range is to be determined. Insimple However, the experimental values are lower than expected value (95% 2- melthylpentane and Thus, the fractional distillation was more effective than the As a safety 20mL of Vokda (Antonov) was placed in a pear-shaped distilling flask for heating until the solution boils, the maximum boiling point of it was 100C.
