1. 1. PurposePurpose

1. Lavel test tubes throgh 2. Follow the instructions for the reaction 3. Write formulas for reactans in your table 4. Predict the products by writing the full chemical equation for

the reaction. 5. Balance the equation. Classify the reaction. 6.Record observations about all details of the reaction. 7. Keep the test tubes containing reactions in a rack. 8.Record any additional observations from changes that

ocurred over the lab period. 9. When finished, clean the equipment you used and put it

away.

EXPERIMENT 6

Station 6:Test tube 6:

Dissolve in water a small quantity of FeCl3 and 5 or 6 drops of NaOH (aq).

EXPERIMENT 1

Station 1:Test tube 1: In one test

tube, mix a few pieces of solid zinc metal with two dopper-fulls of copper (II) nitrate solution. Look closely at the Zn in the tube, and then note the

color of the solution.

EXPERIMENT 2

Station 2:Test tube 2: In a new test

tube, mix one dropper of ammonium hydroxide solution with one dropper of copper (II) nitrate solution.
