Question

electrolytic decomposition reaction. pls explain this to me very easily​

Answer 1

Answer:

The reaction in which electricity is passed to the compound to break it into simpler is called electrolytic decomposition reaction.

Answer 2

$2NaCl$ → $2Na (at Cathode) + Cl_2 (at anode)$

Explanation:

Electrolytic decomposition reaction takes place under the influence of electricity passed into the solution that breaks the compounds into their respective ions.

A general equation representing electrolytic decomposition reaction is -

  AB → A + B

Examples -

• Dissociation of hydrogen peroxide to water and oxygen
• Breakdown of water to hydrogen and oxygen
• Breakdown of $NaCl$ molecule
• Non-spontaneous reactions  

The equations for the chemical reaction are -

$2H_2O$ → $2H_2 + O_2$

$2NaCl$→ $2Na (at Cathode) + Cl_2 (at anode)$

$2AlCl_3$ → $2Al (at Cathode) + 3 Cl_2 (at anode)$

Uses -

1) Industrial preparation of elements like aluminium and sodium

2) In electroplating of elements
