In my experiment I discovered that sugar and salt were polar. The sample of vegetable oil was non-polar. From the data I collected I can say that ethanol's polarity was polar. Ethanol could dissolve in water since water is polar. Hexane would not dissolve in water because it is non-polar and water is polar. NH3 is a non-polar molecule and is would dissolve in hexane but not water. I2 is polar and it would dissolve in water but not hexane. HCl is polar and it would dissolve in water but not hexane. Ionic molecules dissolve in water because it is polar and their polarity is stronger compared to non-polar molecules.
