* Oil and water don't mix: They are immiscible liquids, meaning they form separate layers.
* Filtration relies on particle size: Filtration works by trapping particles larger than the filter's pores. Oil and water are both liquids with molecules that are too small to be caught by a typical filter.
Better methods for separating oil and water:
* Decantation: Carefully pouring off the top layer (oil) after the mixture settles.
* Separatory funnel: A funnel with a stopcock that allows you to drain the lower layer (water) while keeping the top layer (oil).
Let me know if you'd like more details on these separation methods!
