6. You are going to use a dropper bottle to slowly add ethanol to the test tube.
Position the dropper so that the drops run down the side of the test tube. Slowly
add drops until the test tube is half full. The ethanol should form a separate layer
above the filtered solution. Record what you observe.
7. Place the tip of the stirring rod at the point where the two layers meet as shown in
Figure 2. As you gently twirl the rod, bend down so you can observe what is
happening at eye level. Record what you observe.
8. After you dispose of the materials as instructed by your teacher, wash your hands
thoroughly with soap and warm water.
