It does not contain any net charge making it nonreactive. Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and presence of other chemicals (including changes to the pH) of the solution. You desire a little of both. Oil is comprised of long chains of hydrogen and carbon atoms linked to each other. if dna is not soluble in vegetable oil...can use oil instead of ethanol to extract dna/?
