[NewCandle] Rolled Al hydrolysis

[Keith Nagel]

OK, the oxide layer has grown to the point
where the reaction has diminished to just the
occasional tiny bubble. I don't doubt that
drying and heating the Al will get things moving
again, as you'd be breaking the loose oxide
skin by doing that. Either an acid or a base
will do the same, and this experiment seems
to indicate that when you dissolve Al in the
acid or base solution it's the water that's
doing the corrosion and the acid/base just
cleans up the resulting oxide leaving a fresh surface
for more corrosion. Would an anhydrous acid
_not_ corrode Al? And is what's limiting the
reaction now the film thickness or the solubility
limit of the water? I can test this, by replacing
the old water with fresh tomorrow morning and
watch the results.

Hi Keith,

Bubblin!

Well, if it goes like the ones Sam and I have played
with, you should get some occcasional spurts of very
high bubbling amidst the level that you plateau at,
but then in probably 48 to 72 more hours it will begin
to diminish, then at about another 48 hours beyond
that, the Al will turn a gunmetal grey, and the water
will be visibly murky, and the bubbling will slowly
stop.

Now Sam claims that if you take the roll out, let it
drip dry, then bake it in an oven at 300F for a couple
of hours, once back in the water, it will kick in
again with about the same cycle.  MAybe baking cracks
open hydroxide layers or something.

Overall, its kinda novel, but without the "amalgam"
such as KOH or NaOH, its self limiting.
