The correct method for separating a homogeneous mixture containing two liquids is distillation. A homogeneous mixture of two liquids is typically a solution, where the liquids are miscible.
Distillation is a separation technique used to separate components of a liquid mixture by selective boiling and condensation. If the two liquids in the homogeneous mixture have different boiling points, one liquid will vaporize more readily than the other when heated. The vapor is then condensed back into a liquid and collected, achieving separation.
Filtration is used to separate insoluble solids from liquids. Evaporation separates a dissolved solid from a volatile solvent, or separates liquids if one is much more volatile and the other is the desired component (or discarded). Condensation is the phase change from gas to liquid and is a step within the distillation process, not a standalone separation method for a liquid mixture.
