We can separate alcohol dissolved in water by using a separating funnel.
A. True
B. False
Solution
There are different ways of separation of a mixture of alcohol and water. These methods are mainly based on the difference of the boiling points of the solvents.
Complete Step by step Solution:
- Alcohols and water are two types of liquids that are completely miscible with each other. Hence these two liquids cannot be separated by a separatory funnel. The best way to separate them is through fractional distillation.
- Fractional distillation is a process in which the components are separated due to a difference in their boiling points. The chemical components are separated by heating them to a temperature at which one or more components of the mixture will vaporize. It uses distillation to fractionate. The components have boiling points that differ by at least 25 0C at one atmosphere pressure.
- Hence, the answer to the question is false, alcohols and water cannot be separated from each other by using a separating funnel due to the fact that they are miscible with each other.
Hence, the correct answer is option B.
Notes: The separating funnel, also known as the separatory funnel, is used for different liquid-liquid separations based on their densities as the two solvents form an immiscible layer. This principle is also used to separate a solute from a solvent by using another solvent in which the solute dissolves more and is immiscible with the first liquid.
