Metal Reactions

                                                                   Metal + Acid 

In science today we were doing a experiment and we have been learning about Metals and acid and how it all reacts when, we put Metal and Acid together in a tube then after a while it would make a pop sound so we have used magnesium for our metal.  

Equation -   Metal + acid > Metal Salt 

Method -  Light your Bunsen burner  Add your sample of metal to your test tube. Add 2 ml of acid.  Carefully invert the boiling tube above the test tube containing the metal and as shown in the diagram below.  

Conclusion  -   After we did the experiment it made a pop sound. 

                                                                 Glowing Splint 

In science we did another experiment where we had to grab a splint, and then we garbed the splint and light it and put it in the test tube with manganese dioxide in it  once we put that, in there we then put the splint with fire in it with the manganese's dioxide in it after we put it in there it would start to boil. 

Equation -   Metal Oxide + hydrogen Oxide > Metal Peroxide 

Method -  1. Light your Bunsen burner. 2. Add 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. 

Conclusion - After we did this it started to boil when it reacts with the manganese dioxide. 

 

                                                                 Lime Water Test 

The lime water test is where we get test tubes and we well get a hose that well end up moving the, Lime water to the acid after this we well put the lime water in the tube and  it will start to bubble in the tube and it would end up fogging up making more bubbles when we add more acid in it. 

Aim - To Show that carbo Dioxide gas is produced when a metal carbonate reacts with acid. 

Equipment - Two boiling tubes. Delivery tube and bung. Bunsen burner, test tube rack. Wooden splint, a bottle of acid small amount of metal carbonate test tube tongs. 

Method - 1. Light your Bunsen burner. 2. Add a pea sized amount of the metal carbonate into one of the boiling tubes 3. Place this boiling tube into a test tube rack ensure you have the bung and delivery tub e ready. 4. Add 5Ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube. 5. Holding the other boiling tube with your tongs, capture the gas produced as shown in the diagram below. 6. When you think the tube is full, your lab partner should light a wooden splint. 7. Carefully remove the boiling tube from under the deliver tube, taking care to keep it facing upright.  8. Insert the burning splint into the mouth of the test tube.
