Question

In electrolytic decomposition of water in annode what gas is evolved?

Answer 1

Electrolysis of water: Electrolysis of water is the decomposition of water into hydrogen and oxygen due to the passage of electric current through it.
Decomposition of sodium chloride:On passing electricity through molten sodium chloride, it decomposes into sodium and chlorine.
Photo decomposition reaction (Photolysis)


Decomposition of silver chloride:Place a small quantity of silver chloride (AgCl) taken in a watch glass under sunlight for some time. The crystals slowly acquire a grey colour. On analysis, it is found that the sunlight has caused decomposition of silver chloride into silver and chlorine.

Answer 2

On electrolytic decomposition of water in annode hydrogen gas were evolved
