Answer:
d = Hydrogen and oxygen are being formed.
Explanation:
When current is passed through the water electrolysis take place.
Water is splitted into hydrogen and oxygen gas. Because of this formation bubbles are formed.
At cathode:
2H₂O + 2e⁻ → H₂ + 2OH⁻
Cathode is negatively charged and reduction take place on it.
At anode:
4OH⁻ → O₂ + 2H₂O + 4e⁻
Anode is positively charged and oxidation take place on it.
The over all reaction can be written as:
Chemical equation:
2H₂O (electricity) → 2H₂ + O₂
