Question

Explain the process to decompose water into hydrogen and oxygen.

Answer 1

Answer:

Photoelectrochemical water splitting

Again, water is broken down into hydrogen and oxygen by electrolysis, but the electrical energy is obtained by a photoelectrochemical cell (PEC) process. The system is also named artificial photosynthesis

Answer 2

Answer:

The process to decompose water into hydrogen and oxygen is Electrolytic Decomposition Reaction

Explanation:

• First u take plastic mug and do two holes at the bottom of mug and insert the electrodes from the bottom of mug(from holes)
• Fill the mug with water and cover the electrodes by test tubes and add some drops of hydrochloric acid
• Attach the conducting wire between electrodes and 6V battery
• Now,switch on the electricity.
