👉 In chemistry, an efflux is a type of chemical reaction that involves the movement of solutes (such as water or chemicals) from one medium to another. This process can occur in both aqueous and non-aqueous systems. An efflux occurs when solute molecules move out of solution into a more polar phase (like water), whereas an influx occurs when solute molecules move into a less polar phase (like water). The direction of the movement is determined by the polarity of the solvent
