4 Multiple Choice Questions

  1. The separation of the components in a liquid mixture into fractions which differ in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.
  2. the process in which a solid changes directly into a gas
  3. Gravity filtration is used for when the desired product is in solution (usually hot) where as vacuum filtration has the desired product being a solid.
  4. container that can be sealed from the atmosphere and holds a drying agent

4 True/False Questions

  1. Column Chromatographymixture of compounds to be separated is introduced onto the column that is packed with a stationary solid. The solid is continuously washed by a flow of solvent (mobile) passing through the column. The continuous flow of solvent throught the column and the interaction b/w the solid compounds in the mixture, separates the mixture as it passes down the colum.
