any teacher can help me to answer this..
How to write overall ionic equation for electrolysis of dilute HCl?

Tq for ur help 1st..

[Patrick Chai Teck Khiong]

4H⁺ + 4OH^-  -->  2H₂ +  2H₂O + O₂

[Wong Pei Funn]

Tq vy much Mr Chai..

How about this answer : 2 H2O --> 2 H2 + O2  ?

[Lim Tze Khai]

That is correct. Actually that is the final ionic equation after removing 2 water molecule from left and right side of the equation.

This is because electrolysis of dilute HCl involving decomposition of water molecule to Hydrogen gas and oxygen gas.

[Patrick Chai Teck Khiong]

Mr.Lim, isnt that overall ionic equation need to involve the ions that take part in the reaction?

[Sim Thiam Huat]

Just in short, overall ionic equation must contain ions but no electrons. So Mr. Chai's answer is the correct one.

Sgt sgt setuju dgn Mr Chai n Mr Thiam
