Interpretation:
The reason to obtain only one liquid phase with no interface after the solution is shaken second time should be explained.
Concept introduction:
Immiscible liquids are the liquid system that contains two solvent insoluble with each other and consists of two phases. As both the liquid form a separate layer and does not interact with each, therefore, they are independent of each other and contribute to their own characteristics. Oil and water form two different layers, when mixed with other so these are immiscible in each other.
Explanation of Solution
The aqueous solution of two solvents contains a non-polar ethyl ether and highly polar water. Both the solvents are immiscible with each other due to a very large difference in their density.
As diethyl ether is less dense than water it forms an upper layer in extraction equipment while the water forms a lower layer and solute distributed between aqueous and organic layer according to their solubility. After removal of lower layer, only diethyl ether remains in equipment and addition of another
