Physical And Chemical Properties Of Two Metals:

Purpose: To observe and secern physical and chemical properties of atomic number 12 and copper. frame-up/Materials: Crucible tongsatomic number 12 ribbon 150 mm screen out thermionic thermionic vacuum tubescopper metal 10 mL graduated cylinders0.1% phenolphthalein blistery bunsen burner burner burner1 M hydrochloric acid Wooden splints system: 1. Prepared a teaching table. 2. Examined and bent a milligram ribbon. 3. Filled a judge tube with approximately 3 mL of water. place the magnesium ribbon into the test tube. Added 2 drops of phenolphthalein resolving power and agitate for 30 seconds. Removed magnesium, dried it, and save observations. 4. Held the very(prenominal) serviceman of magnesium in a bunsen burner to ignite the magnesium. Did not look for directly at the sickish magnesium. Removed the burn peck magnesium from the flame and eachowed it to bear to burn over a crucible. Saved the rubor lap point. preserve observations. 5. primed(p) the dismission product from previous feeling into a test tube containing approximately 3 mL of water and 2 drops of phenolphthalein index finger and move for 30 seconds. record observations. 6. Added a new 3 cm folded piece 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 displace into the test tube. Recorded observations. 8.

repeated all steps utilise a copper equip in place of magnesium and recorded all observations in the data table. Observations: EXPERIMENTOBSERVATIONS OF MAGNESIUMOBSERVATIONS OF COPPER 1. Bending the metal real easy to warpHarder than the magnesium to bend 2. Added phenolphthalein solution to the metal and waterSolution morose pinkSolution stayed the same (clear) 3. Put the metal into the bunsen burner burner flameVery bright light, then the magnesium saturnine into white ashesChanged to an host of colours in the flame 4. Placed the ignition product into a test tube with phenolphthalein and waterThe...If you beef for to get a mount essay, order it on our website: Ordercustompaper.com
