Physical And Chemical Properties Of Two Metals:

Purpose: To observe and identify physical and chemical properties of nuclear number 12 and copper. Apparatus/Materials: Crucible tongsmagnesium ribbon cl mm turn up thermionic tubescopper coat 10 mL graduated cylinders0.1% phenolphthalein acid etna burner1 M hydrochloric acid wooden care fors Method: 1. Prepared a information table. 2. Examined and bent a magnesium ribbon. 3. Filled a test tube with near 3 mL of water. aim the magnesium ribbon into the test tube. Added 2 drops of phenolphthalein solution and agitate for 30 seconds. Removed magnesium, desiccated 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 flare out and eachowed it to continue to burn over a crucible. Saved the firing intersection point. Recorded observations. 5. Placed the firing off product from introductory 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 component 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 step using a copper wire in place of magnesium and recorded all observations in the data table. Observations: EXPERIMENTOBSERVATIONS OF MAGNESIUMOBSERVATIONS OF slovenly person 1. Bending the metal Ver! y easy to warpHarder than the magnesium to obviate 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 sporty 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 model a full essay, order it on our website: OrderCustomPaper.com
