Justify why electrolysis of water is a chemical irreversible change?

Answer 1

A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen gas.

Answer 2

Electrolysis of water involves the decomposition of water molecules into hydrogen and oxygen gases through the passage of an electric current. This results in a chemical reaction that cannot be easily reversed by simply recombining the hydrogen and oxygen gases back into water. The process requires energy input and irreversible transformation of the water molecules into different chemical substances.

Answer 3

Because oxygen and hydrogen molecules combine to make h2o meaning water and it cannot be seperated again.THATS THE FINAL ANSWER.

Answer 4

No, the process can be reversed by electrolysis,.
