Part 2 In Part 1 you found that one kind of alcohol, ethanol, is extremely soluble in water, thanks to its OH group. Naphthalene is obtained from either coal tar or petroleum distillation and is primarily used to manufacture phthalic anhydride, but is also used in moth repellents.Exposure to naphthalene is associated with hemolytic anemia, damage to the liver and neurological system, cataracts and retinal hemorrhage. gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution OVERVIEW Test each substance listed on the report sheet to see whether they are soluble in water, in cyclohexane, or in neither.
