Metal Reactions

 1. Metal + Acid = Metal Salt + Hydrogen

Magnesium + Sulfuric Acid = Magnesium Sulfate + Hydrogen

Method: 1. Light bunsen burner. 2. Add your sample of metal to your test tube. Add 2 ml of acid. 3. Carefully invert the boiling tube above the test tube containing the metal and acid. 4. Hold the tubes together for few minutes, allowing time for the inverted boiling tube to fill with gas. 5. When you think the tube is full, your lab partner should light a wooden splint. 6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the boiling tube. 

2. Metal + Oxygen = Metal Oxide

Magnesium + Oxygen = Magniseum Oxide

Method: 1. Light bunsen burner. 2. Hold your piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of magnesium. 3. Place the other end of magnesium into the Bunsen flame (at the top of the blue flame). 4. When the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes.

3. Metal Oxid +  Hydrogen Peroxide = Metal Hydroxide + Oxygen

Manganese Dioxide + Hydrogen Peroxide = Manganses Hyrdoxide + Oxygen

Method: 1. Light your bunsen burner. 2. Add the manganese dioxide to the boiling tube and place it in your test tube rack. 3. Add 2ml of Hydrogen peroxide. 4. Light a splint and let it burn for a while. 5. Blow the splint out and insert the glowing embers into the mouth of the boiling tube. It should light back up

4. Metal Carbonate + Acid = Metal salt + Water + Carbonate

Method: 1. Add a pea-sized amount of the melt carbonate into one of the boiling tubes. 2. Place this boiling into a test tube rack. Ensure you have the bung and delivery tube ready. 3. Add 5ml of acid into the boiling tube and quickly insert the bung and delivery and tube into the mouth of the boiling tube. 4. With the other boiling tube hold it with tongs, capture the gas produced with the lime water.
