Answer:

Apply electricity to the water.

Explanation:

Water can be made to decompose by addition of electricity to it. Electric currents makes water undergo a decomposition reaction into subsequent compounds.

  • The process is achieved and commonly called electrolysis of water.
  • It involves the passage of electricity through acidified water.
  • The current causes the water to decompose.

 

 The reaction equation is given as shown below:

                   2H₂O →  2H₂  +  O₂
