Taressa Cade Eight Metals lab Mr. Clark 3/3/08 Identify Eight Metal Ions by Reactions with Anions Beginning question How can metal ions be identified by the chemical reactions with anions? My prediction is the metals ions can be identified by color changes and formation of precipitate that the anions cause when mixed together. Safety Wear goggles Know hazards of chemicals being used Dispose chemicals properly Procedure 1. Fill wells/test tubes two-thirds full with .1M nitrate solutions of these metal ions: A1- Co, A2- Cu, A3- Fe, A4- Co, A5-Zn, A6-Mg, B1-Ba, B2-K 2. Fill following wells three-fourths full with these solutions: D1- .5M Na2SO4, D2- .5M Na2S, D3-KSCN, D4- 4M NaOH, D5- NH4OH, D6-.5M NaI 3. Wash 8 small test tubes and add 10 drops of distilled water to each. 4. Add 2 drops of .1M nitrate solution from step 1 to each circle in a vertical column on the reaction sheet and to one of the test tubes from step 4. these tubes will be used in step 14. 5. Add 2 drops of Na2SO4 to all solutions from step 1. Observe and record you observations on the report form. Write formulas in appropriate spaces. (Dispose, wash, and refill all wells/test tubes between each step.) 6. Add 2 drops of Na2S to all solutions from step 1. Record observations. 7. Add 2 drops of KSCN to all solutions from step 1. Record observations. 8. Add 5 drops of 4M NaOH solution and 35 drops of water to well C4 to create a . 5M NaOH solution. Stir solution with micropipette.
