The one with higher melting point would condense on the columns and move back to the original solution. skin 5% cyclohexane) due to the high set temperature of hot plate at the beginning. Distillation of mixtures may or may not produce relatively . Distillation is a method of separating two volatile chemicals on the basis of their differing boiling points. In the simplest terms, a distillation involves boiling a liquid, then condensing the gas and collecting the liquid elsewhere. Briefly describe how a fractional distillation separates volatile organic liquids. asimpledistillationapparatus M.Tham,lorien.ncl.ac/ming/distil/distilop.htm, Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01.
