How can you cause a decomposition reaction of water?
O Heat up the water.
O Add salt to the water.
Apply electricity to the water.
If you wait long enough it will decompose on its own.

Answer 1

Apply electricity to the water.

Step-by-step 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
