What are the steps by step procedure in performing electrolysis?
Answers
The electrolyte and the electrodes used in electrolysis form an electrolytic cell. When electricity passes through an electrolyte, the positive ions of the electrolyte move towards the cathode (negative electrode), where they gain electrons to become a neutral substance.
This is what happens during electrolysis:
- Positively charged ions move to the negative electrode during electrolysis. They receive electrons and are reduced .
- Negatively charged ions move to the positive electrode during electrolysis. They lose electrons and are oxidised .

STEP 1: GETTING THE STUFF
STEP 2: BUILD THE CELL
STEP 3: BAKING SODA-WATER MIXTURE
STEP 4: SETTING UP THE CELL
STEP 5: THE SCIENCE OF ELECTROLYSIS
STEP 6: TROUBLE SHOOTING
The materials you will need for this experiment are:
baking soda (it used to be salt but then I was informed that I may have been producing chlorine gas)
Hot water (enough to fill your container of choice)
a container preferably air-tight and definitely clear
a pair of screws (these will act as the electrodes you pass the
current through)
a battery (a nine volt will do nicely for your first try)
Space to work (I barely had any and that made it a lot tougher)
