That’s because oil is nonpolar, and water is polar. These terms describe the arrangement of charges in their structure: nonpolar means a molecule has no net charge, polar means it does. The polarity of a molecule influences the way it interacts with other molecules.  We tend to think of two ‘like’ substances, be they nonpolar like two different oils, or polar like water and vinegar, as mixing completely, but that’s not entirely true in all cases.</span></p> Thu, 05 Jul 2018 18:08:22 +0000 Ada McVean B.Sc. 7162 at /oss
