Detailed Solution

The above statement is false.
Filtration is the process of separating insoluble solid particles from the solution by using filter paper or any other filtering device. Oil is insoluble in water but also liquid; therefore, it cannot be separated by filtration. Decantation is a method for separating oil and water mixtures. Decantation is the process of transferring the upper layer to a different vessel without disturbing the lower liquid. To separate the immiscible liquids, use a separating funnel. The two liquids are placed in the funnel and allowed to settle out and form two layers for a short period of time. Then, the funnel's tap is opened, allowing the bottom liquid to flow. The two liquids would be split apart.
The corrected statement would be, “A mixture of oil and water can be separated by separating funnel or decantation”.
