When a mixture of soluble liquids is heated all liquids are evaporated. The liquid with the _______________boiling point, however, forms the greatest percentage of vapor. A _________________column is needed to further separate the mixture. As the vapor moves up the fractionating column it becomes progressively ____________with the component that has the lowest boiling point. This is due to the vapor mixture continually condensing and _____________as it moves up the column. A thermometer is used to measure temperature of the gaseous fractions before they _____________The liquid with the lowest boiling point will be the first 'fraction' or portion of the _______________
