Ethanol plus water
WebScience. The reason is that for the ethanol-water mixture, the partial molar volume (the additional increase in volume upon addition of a mole of a substance) is always less than partial molar volume for either pure component. In other words, for any molar fraction of ethanol adding a given volume of water will result in a smaller increase in ...
