Methanol ethanol mixture freezing point
WebA mixture of miscible liquids typically doesn't behave as the separate components. At the point at which freezing begins (which may be higher or lower than that of either component), both the frozen material and the liquid still contain both components. The frozen is enriched in the higher melting point component and the liquid is depleted. WebThere are 3 moles in the mixture in total. 2 of these are methanol. The mole fraction of methanol is 2/3. Similarly, the mole fraction of ethanol is 1/3. You can easily find the partial vapor pressures using Raoult's Law - assuming that a mixture of methanol and ethanol is ideal. First for methanol: \[ P_{methanol} = \dfrac{2}{3} \times 81\; kPa\]
