Put 5 mL of water into a test tube and add 1/2 teaspoon of sodium acetate. Shake the solution. To this solution add 1 crystal of sodium acetate and shake the solution. ( A crystal is just a tiny piece of sodium acetate.) Does the crystal disssolve? What kind of solution is this? 2. To the solution you have just made, add 2 1/2 teaspoons of sodium acetate and shake. continue adding sodium acetate until there is a layer of undissolved sodium acetate on the botton of the test tube. Pour off the solution only into a second test tube, being careful not to pour any solid along with it. Discard the solid that remains. Now add one crystal of sodium acetate to this solution, shake and observe. Does the crystal dissolve? What kind of solution is this? 3. To the solution you have just prepared, add about 2 1/ more teaspoons of sodium acetate and shake. There should be quite a bit of solid that does not dissolve in the solution. Clamp this test tube to a ring stand at an angle. YOUR TEACHER MUST CHECK THE SETUP BEFORE ANY HEATING CAN OCCUR!!!! Heat the solution by moving the Bunsen burner up and down the length of the test tube. Heat until all of the solid has dissolved. Turn the test tube and its contents so the tube is vertical. Now let the solution cool to room temperature (you can hasten this process by holding a cold water bath around the tube, but whatever you do, DO NOT DISTURB THE COOLING TEST TUBE). When the tube has reached room temperature, add one crystal of sodium acetate. What happens to the solution? What type of solution is this? Finally, touch the outside of the test tube.
