Thanks for trying to assist but I know about sulphuric acid.
.............
It's sodium carbonate dissolved in water in plastic container.
Connect a car battery to the object to be de rusted and the other
wire to a stainless steel anode in the water.

Sulphuric acid - H2SO4 - produces an acidic solution when it
dissociates in water
Sodium carbonate - Na2CO3 - often hydrated as Na2CO3.xH2O -
produces a basic solution.

You've given me a good laugh for today though.

But not as much as your lack of comprehension! He never even
mentioned sulpuric acid until someone else did...and the above was
two separate sentences, not a combined description of sulpuric acid.


But the OP did say, and I quote: "sodiam carbonate/water/car battery",
which made it look to me like he was planning to put 'sodiam
carbonate' (sic) in a car battery, for some de-rusting purpose. Hence
the warnings that I gave about H2SO4. It turns out he had a reasonable
plan, but he did ask his question in a somewhat daft way.
