I added enough water to the mixture to make it equal to the first mixture, and the phase separation came clearly into view. Is hexane miscible with ethanol? For example, tetrahydrofuran (THF) and water are miscible. Therefore, it is safe to say that these data would gives you some insight to what you are looking for. Anhydrous ethanol and hexane are "just barely miscible"; the next step up in polarity (anhydrous methanol) is, $\pu {12.92 cal^{\frac{1}{2}}cm^{\frac{3}{2}}}$, $\pu {7.24 cal^{\frac{1}{2}}cm^{\frac{3}{2}}}$, $\delta_{\ce{MeOH}}=\pu {14.28 cal^{\frac{1}{2}}cm^{\frac{3}{2}}}$, $\pu {1.36 cal^{\frac{1}{2}}cm^{\frac{3}{2}}}$, $\delta_{\ce{H2O}}=\pu {23.5 cal^{\frac{1}{2}}cm^{\frac{3}{2}}}$, $$ 23.5\left(\frac{4}{100}\right) + 12.92\left(\frac{96}{100}\right) = 13.34 = \delta_{96\%\ce{EtOH}} \lt \delta_{\ce{MeOH}}$$, $$ 23.5\left(\frac{10}{100}\right) + 12.92\left(\frac{90}{100}\right) = 14.0 = \delta_{90\%\ce{EtOH}} \lt \delta_{\ce{MeOH}}$$, $\delta_{90\%\ce{EtOH}} \lt \delta_{\ce{MeOH}}$, Miscibility of Hexane and Ethanol (Anhydrous vs 96%), https://doi.org/10.1016/0300-9440(96)81583-9, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI, Polarity of alcohols and their miscibility in water, Miscibility gap of heptane-methanol mixture, Short story about swapping bodies as a job; the person who hires the main character misuses his body, Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). In crudest terms it is the molecule in the mixture with the highest concentration. The 1st was done for you ax an example. For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Ethanol does on a molecule by molecule basis have stronger intermolecular forces between itself and water than methanol and water. So far, we've been thinking about how one molecule could interact with another molecule of the same compound to form a liquid or a solid. { "0Demos_List" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.
