HI,
This is my fist post on this greet forum
I have a question
As you know NaOH and HCl are product by electrolysis of sodium chloride
On other wards NaCl + Electrical energy=NaOH + HCl (H2 + Cl2)
Now my question: Is there any way to product Electrical energy from NaOH & HCl

Thanks a lot

Technically you can make electricity from any redox reaction. In this case it means you can make electricity from H₂ & Cl₂ reaction, but you already reacted them to make HCl - so you are not left with many options.

No, not every reaction is reversible.  Consider:  gasoline + oxygen  H₂O + CO₂ + forward automobile motion  to simplify greatly.  But you can't put a car up on blocks, spin its wheels backwards, exhale your CO₂ and H₂O rich breath into the tailpipe, and get the tank to refill with gasoline.  Technically, CO2 and H2O are constantly converted into biomass worldwide, and that biomass can be partially decomposed into petroleum, and that can be made into gasoline.  But sometimes, we need multiple steps to insure the energy is transferred properly.  See also, the Solvay Process. http://en.wikipedia.org/wiki/Solvay_process
