Question
A mixture of two miscible liquids cannot be separated by:
- Simple distillation
- Separating funnel
- Steam distillation
- Fractional distillation
Hint:
Separating funnel separates immiscible liquids.
The correct answer is: Separating funnel
- Separating funnel separates two immiscible liquids based on density difference.
- Steam distillation is a separation process that consists in distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
- Simple distillation is a distillation separates a liquid from a solution simply by heating.
- Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C (45 °F) from each other under a pressure of one atmosphere.
