Procedure Part 2:

Now we will measure the current drawn through the hydrogen generator as well as the final temperature of the water. Then we will burn the gas which is produced.

Step 4:

• Turn the meter to the current range and insert it in series with one of the electrode leads. Measure the amount of current required for the electrolysis process. Record the value.

Step 5:

• When the small bottles are filled with gas up to the top of the electrodes, stop the process.
• At this time measure the temperature of the water in the big bottle. Record the measurement.
• Record the total time of the process.
  
  

 

 

Step 6:

• Light the outlet of the mixer valve. (The gas flame will not last long before the hydrogen and oxygen are used up.)
