Question

is what does the given diagram represent?
ii, which gas is produced at anode?
in Does Pure water coduct electricity? why?
i, what should be added to initiate electrolysis
in water?
V what will be the reaction at cathode?​

Answer 1

1. oxygen
2. Pure water does not conduct electricity. This is because pure water do not contain any salts. Pure water can conduct electricity when common salt is added to it, as salt solution is conducting in nature.
3. By adding electricity to water and providing a path for the different particles to follow, the water can be separated into hydrogen and oxygen. In this experiment you will be taking a sample of salt water and add a flow of electricity to it (the electrolysis).
4. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and cathode is the negative electrode. The reaction at the anode is oxidation and that at the cathode is reduction. The electrons are supplied by the species getting oxidized.
