Miscibility
| Formula / Notation | Miscibility: binary liquid pairs mix in all proportions; A and B miscible if ΔG_mix < 0 |

| Also Known As | Miscibility, complete miscibility, mutual solubility |
What is Miscibility?
The property of liquids to mix in all proportions without separating into two phases. Polar liquids are generally miscible with polar liquids (e.g., ethanol and water), and nonpolar with nonpolar. Partial miscibility occurs over limited composition ranges.

Miscibility determines which solvents can be used together, guides solvent selection for reactions and extractions, is key in designing antifreeze formulations (ethylene glycol in water), pharmaceutical co-solvent systems, and in food processing (fat and water immiscibility is the basis of emulsion …
Miscible solvent mixtures can have flash points different from (often lower than) either pure component — increasing fire risk. Miscible toxic solvents (DMSO miscible in water) can carry dissolved toxins through skin barriers. Azeotrope formation in miscible systems affects distillation efficiency.
The formula or notation for Miscibility is: Miscibility: binary liquid pairs mix in all proportions; A and B miscible if ΔG_mix < 0
