Metal Reaction

Testing for Hydrogen Gas, Sound of POP test.

The aim is to make a metal oxide and observe the difference and properties of the product compared to the reactants.

1. MEtal + Acid

• Equation 

Metal + Acid = Metal salt + Hydrogen

Magnesium + Sulfuric Acid  = Magnesium sulfate

•  Method 

1. Put 2ml of sulfuric acid and a piece of magnesium metal inside the test tube.

2. Boiling tube inverted to collect any of the gas that is produced.

3. light up a splint and hold the boiling tube that has gas inside 

•  Conclusion

When I inserted the flaming splint inside the boiling test tube while the Hydrogen gas was inside, It made a pop sound so it means that there oxygen that is trapped in a boiling tube. 

Testing Out FOr the Presence of oxygen.

Aim: To carry out the test for the presence of gas (O2)  

Equipment: A pea-sized amount of manganese dioxide (MnO2), Boingtube, bottle hydrogen peroxide (H2O2), Woden splint, Bunsen burner, test tube rack, and don't forget a safety glasses.

Method

1. Add manganese dioxide in a boiling tube. 

2. add 2 ml of hydrogen peroxide.

3. lit up ur splint with a bunsen burner.

4. Blow up ur burning splint and insert the glowing embers into the mouth of the boiling tube.

5. You will see the tip of the splint will get reignite and it's bery bery aswesome!!!.

Thae Conclusion:

When the acid was added into the boiling tube I can see a bubble of gas that was released.
