Procedures

                 
Step 1: Label the wells of two well plates with the letters A-L. In one well plate, place a sample (two small scoops or two small pieces) of each substance in the well that corresponds with the label. This will be your source of substances for all your testing.
Step 2: Place a small amount (one or two grains, or a small piece) of a substance on a glass slide. Examine the sample carefully with magnification. Record your observations.
Step 3: Crush the sample by rolling a small test tube over it a few times with light pressure. Again examine the sample carefully with magnification. Indicate whether the sample was malleable, able to be deformed. Record your observations.
Step 4: Repeat steps 2 and 3 for all the chemical samples. Once finished, move on to Step 5.
YES
Step 5: Test the conductivity of the solids in the well plate using a conductivity tester. Record the results.









 
good job, now do steps 2 and 3, then move to the next step.
follow the arrow.
 
Step 6: Place a small amount (just the amount that fits on the tip of a wooden stirring stick) of each chemical in the corresponding well of the second well plate. Add approximately 1 mL of deionized water to each well. Stir with a toothpick, Record the solubility as soluble, slightly soluble, or insoluble.









Step 11: Record the melting point as very high for any that did not melt with the Bunsen burner flame.
Step 10: Take a small amount of any four samples that did not melt in the previous step and place them in an aluminum dish. Place the dish on wire gauze above a Bunsen burner flame. Wait for 1 minute and record any that melt in that time as having high melting points. Repeat until all samples that did not melt at a medium or low temperature that have been tested at this high temperature.
Step 9: Take a small amount of any four samples that did not melt in the previous step and place them in an aluminum dish. Place the dish on the hot plate at its highest setting. Wait for 1 minute and record any that melt in that time as having a medium melting points. Repeat until all samples that did not melt at a low temperature that have been tested at this medium temperature.
Step 8: Take a small amount of four samples and place them in an aluminum dish. Place them on a hot plate at a medium heat setting. Wait for 1 minute; record any that have melted as having low melting points. Repeat until all samples have been tested at this temperature. Note: Sample D may be heated only under a fume hood.
Step 7: Test the conductivity of the liquid in each well. Record the results.









Step 12: On the basis of the collected data, determine what type of solid each sample is. Provide an explanation for each sample.
