Could the separation in this experiment have been done in a different order? For example, if the mixturewas first extracted with water and then both the extract and the insoluble residue were heated to dryness,could you determine the amounts of NaCl, NH,Cl, and SiO, originally present? Why or why not?Consult a handbook to answer these questions.2. How could you separate barium sulfate, BaSO4, from NaCl?3. How could you separate magnesium chloride, MgCl2, from silver chloride, AgCl?4. How could you separate tellurium dioxide, TeO2, from SiO,?5. How could you separate lauric acid from a-naphthol? (See Table 3.1.)
