pls explain why electrolysis of water & dilution of concentrated acid is achemical change?

if dilution is a physical change then why?

Since electrolysis makes water to become two gases, it cannot be possible for the two gases to become liquid. Moreover, it needs a perfect ratio for the mixing to take place. A physical mixture doesnot need these. So this is a Chemical Change.
I hope this helps to solve your answer.

During electrolysis of water,it decomposes to form hydrogen and oxygen showing that it is chemical change.Also the properties of the products and water are different.
Dilution of concentrated acid isn't achemical change.It is a solution. During dilution,only the amount of solute changes.so it is only a physical change.

well lets do a practical here
just hold both the ends of electric wire and see electrolysis of your body happening and then u will feel the chemicals changing in your body

electrolysis is a chemical change b'cos then water transforms into two gases and loses its properties. the gases cannot be formed again into water by physical methods. i don't think that dillution is a chemical change

dilution is a physical change
electrolysis is a chemical change cos new products r formed
