QUESTIONS 1. Could the separation in this experiment have been done in a different order? For example, if the mixture was 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,CI, 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, Teoz, from SiO2? 5. How could you separate lauric acid from a-naphthol?

Separation of Components of a Mixture
A. Determination of the mass percentage of ammonium chloride
• Mass of evaporating dish and original sample………….. 51.9109g
• Mass of evaporating dish………………………………….48.8729g
• Mass of original sample………………………………………..2.0380g
• Mass of evaporating dish after sublimation of Ammonium chloride
50.6615g
• Mass of ammonium chloride………………………………….. 0.2494g
• Percentage of ammonium chloride
Mass of evaporating dish and original sample – mass of evaporating dish = mass of
original in g


50.9109g – 48.8729g = 2.0380g

Mass of evaporating dish and original sample – mass of evaporating dish after subli...
