I found that among mentioned substances acetone and ethylene glycol are soluble in water‚ therefore we can say that they are polar substances. Besides‚ I observed that biphenyl‚ butyl acetate‚ glycerol and motor oil are nonpolar substance. These compounds were soluble in hexane. Meanwhile‚ magnesium oxide and sodium bromide did not dissolved in either water nor in hexane. Moreover‚ Iodine and aspirin acted different than what I expected
