Electric Gas                            

Question:
Can we break down water H20 into its gas elements two parts Hydrogen and one part Oxygen using direct current of a battery?

  

Hypothesis:

We predict that we will be able to separate the hydrogen and oxygen into separate test tubes and then show hydrogen is in one tube because hydrogen burns in the presence of oxygen.


CONCLUSION:
Hydrogen can be separated from oxygen and it is proven by the popping noise showing the presence of hydrogen in the test tube.

Materials: 

Picture

  • a sequence of batteries to supply the power
  • Safety goggles
  • Platinum electrodes
  • Alligator clips
  • Test tubes
  • basin of salted water
  • splints
  • test tube clamps 
  • controlled flame

Safety Procedures

-Our controlled flame will be a candle lit with adult supervision, this candle will light the splints that will prove our Hypothesis
-Safety goggles will be supplied and worn by each participant and observers
-The test tubes used are small test tubes and we are only planning on collecting a small amount  hydrogen so the pop from the hydrogen is minimal.

Procedure:


  1. Fill basin or small tub with hot water and add salt to water 
  2. Fill up the test tubes with water and clamp to the test tube holder
  3. Connect the batteries to get the current going in the water to separate the hydrogen and oxygen
  4. Observe the test tubes filling with hydrogen and or oxygen and the water will exit the test tubes
  5. An adult will ignite the candle 
  6. Carefully remove the test tube filled with hydrogen and place finger over the opening.
  7. A splint will be lit .  The test tube with hydrogen needs to be turn upright at a 45 degree angle so that the hydrogen can meet the oxygen and the lit splint will be inserted at top of the test tube and there will a small popping sound thus proof of the presence of hydrogen
