Before I start hunting around for washing soda I would like to check if sodiam carbonate/water/car battery will dissolve rust please. Also I have had no luck so far in finding washing soda/sodiam carconate so perhaps someone knows which firm to ring for sodiam carbonate.
Thanks very much
1) it's SODIUM CARBONATE (DECAHYDRATE Na2CO3=B710H2O), Washing Soda. 2) it is NOT used in batteries, they use Sulphuric ACID (H2SO4). 3) Sodium Carbonate is a strong ALKALI. 4) Sulphuric Acid will dissolve rust, AND ALL THE REST OF THE METAL. 5) Sulphuric Acid will dissolve YOU. 6) Mixing Alkali and Acid will result in a violent foaming reaction - the gas may be toxic. The properties of the foam will depend on the relative strengths of the two reagents and anything else added, like the container!
If you don't understand this, please don't play with the chemicals, but use a proprietary rust solution. Sulphuric Acid is one of the most dangerous common chemicals, Washing Soda is pretty nasty too.

It's "sodium".
And sodium carbonate will not do anything to rust. Nor water. I assume "car battery" is dilute sulpuric acid which is not actually a rust treatment, either.
I suspect your email name is poorly chosen.
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.
Really - you know all about sulphuric acid and that it's sodium carbonate dissolved in water. That's a new one on me - on both counts!
Is English your first language?
"It" normally refers to the last noun used, in this case "sulphuric acid", so what you're *saying* here is "sulphuric acid is sodium carbonate dissolved in water". This is patent nonsense, so is it what you meant to say?
The only way to convert rust back to steel uses a very large and expensive piece of equipment called a "blast furnace".
What is it you're trying to achieve?
This actually has nothing to do with car batteries, does it?
Are you asking a question about electrolysis?

It's available in Asda. Blue bag, about a quid, somewhere near the washing stuff iirc.
Dunno.
Cillit Bang is good for rust though.
sponix
you've found an application for cillit bang which actually works ?
if I were you I'd contact their marketing dept for a big, fat, commission :o)
Didn't say though how Cillit Bang is good for rust, removing it, creating it or just giving it a good polish.
all three, obv !!
OK, so you are planning to use a solution of sodium carbonate as an electrolyte and use the battery to power the removal of Ferric Oxide and Ferrous Oxide (I can remember which is normal rust, probably both).
Seems plausible, I'm not sure if there is a better cost effective electrolyte. This article suggest you may have a point:

It's sulphuric.
Stop being a patronising, pedantic, condescending, pompous ass for a minute and note that even you too are susceptible to mispellings
Ooops...I misspelt misspellings...lol.
*plonk*
^^^^^^^^^^^ ;-)
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.
