The suggestion is to use an electrolyte made up of a 60/40% mix of
sulphuric acid/water, plus 30g/litre of glycerine (glycerol?).

Q's:

It's difficult to buy concentrated sulphuric acid in a smallish quantity
at a reasonable price. Can battery acid (35%) be used instead?

Is glycerine the same stuff as glycerol?

Isn't glycerine a liquid? Why is it expressed in terms of weight?

What's the glycerine/ol for?

Thanks

Spit-ballin here...

De-plating is, in principle, the exact electro-chemical opposite of plating.
There is a fair amount of experimental lattitutde in the plating process
(art??), and f'sure there is much more lattitude in the de-plating
process--ie, much less critical.

So the ""answers"" to your Qs are
Sulf. acid: Yeah, battery acid should work. Acid drain cleaner should work!
Glycerin (no "e") = glycerol.
'tis a liquid, but wt measure is interchangeably used w/ vol. by chemists,
regardless of reagent state--they have lots of neat accurate scales floating
around--ask any college student who wound up w/ a triple-beam balance in his
dorm room.... no no, not for *that*....
..
Here, I'd guess it's use might be to help precipitate dissolving nickel, but
in principle, it's not necessary.
The acid is likely not strictly necessary either; these items/concentrations
were proly found to make things go faster.
But mebbe not!

In essence, when de-plating, you're pretending that the thing you're
de-plating is the source electrode, and that you are *plating* the *other*
electrode. Fergot what's what ito of anode/cathode, but you get the idea...

I'm told the job is anode when de-nickelling.
