what are electrolysis decomposition reactions? discuss the electrolysis decomposition of water with the help of an activity.

Answer:
ELECTROLYTIC DECOMPOSITION
means breaking in ions when electricity is passed in a solution. ... When we pass electricity in a solution of Na-Cl and water NaCl is broken in ions. Or electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to an electric current being passed through the water
Take a glass beaker fix two electrodes. The positive electrode acts as anode &negative electrode act as cathode. Fill 1/3 of beaker with water. Take two test tubes. Insert on electrodes. Observe the level of water in the test tubes. Connect the electrodes to a battery. Pass the electricity for a period of time. Later switch off the current and observe the level of water in test tubes. The level of water in the test tubes is decreased. The free space in the test tubes is filled with H2 & O2 gases. Oxygen gas is evolved at anode and hydrogen gas released at cathode.
