Physical And Chemical Properties Of Two Metals:

Purpose: To observe and identify physical and chemical properties of atomic number 12 and copper. Apparatus/Materials: Crucible tongsmagnesium ribbon one hundred fifty mm streamlet thermionic tubescopper surface 10 mL graduated cylinders0.1% phenolphthalein acid etna burner1 M hydrochloric acid woody splints Method: 1. Prepared a information table. 2. Examined and bent a magnesium ribbon. 3. Filled a test tube with rough 3 mL of water. discover the magnesium ribbon into the test tube. Added 2 drops of phenolphthalein solution and agitate for 30 seconds. Removed magnesium, dried-out it, and recorded observations. 4. Held the same serviceman of magnesium in a bunsen burner to ignite the magnesium. Did not look directly at the anxious magnesium. Removed the burn down magnesium from the blast and eachowed it to continue to burn over a crucible. Saved the excitation intersection point. Recorded observations. 5. Placed the liberation product from old step into a test tube containing approximately 3 mL of water and 2 drops of phenolphthalein indicator and move for 30 seconds. Recorded observations. 6. Added a new 3 cm folded dapple of magnesium ribbon to a test tube containing 1 mL of 1 M hydrochloric acid and ascertained for 30 seconds. Recorded observations. 7. Tested the gas produced with a burning splint placed into the test tube. Recorded observations. 8.

Repeated all steps using a copper wire in place of magnesium and recorded all observations in the data table. Observations: EXPERIMENTOBSERVATIONS OF MAGNESIUMOB SERVATIONS OF copper 1. Bending the metal ! Very easy to warpHarder than the magnesium to convolute 2. Added phenolphthalein solution to the metal and waterSolution morose pinkSolution stayed the same (clear) 3. Put the metal into the Bunsen burner flameVery bright light, then the magnesium saturnine into white-hot ashesChanged to an array of colours in the flame 4. Placed the ignition product into a test tube with phenolphthalein and waterThe...If you call for to decease a full essay, order it on our website: OrderCustomPaper.com
