Lab Procedure 1. Label your 8 test tubes, 1-8 corresponding to the reactions listed in the data sheets. 2. Mix approximately equal amounts of each of the provided 0.5M solutions required for each reactio Table 1, using a dropper full of each solution. DO NOT CROSS CONTAMINATE DROPPERS. 3. Use a piece of parafilm to cover each test tube and give it a shake to mix. 4. In observations, record whether or not a ppt actually forms for each mixture. Comment on differe quantity and or if you noticed any change in temperature of the test tube. For any test tubes that y see a precipitate immediately, leave sit for about 5 min before you make a final observation. 5. Pour the calcium, iron and aluminum solutions down the sink and the zinc and copper solu the waste container in the fume hood. 6. Rinse out the test tubes, and brush with a test tube brush and leave upside down to drain in your DATA 1. Ca(OH)2 Eqn for formation: PPt prediction Observations @ 298 K el pe 2.
