Always happy to oblige, and I won’t even do it on an AGW related topic, though I’ve got plenty of them stored up

Today is the Sophie’s Choice day on our forum: it’s between 9/11 conspiracy, the envelope problem, and sports. Can somebody start a new thread on something else?
Cool stuff and I didn’t even have to go far to find it.
Just imagine it. . . . . . . our oldest common ancestor.
ScienceDaily (Feb. 7, 2012) — It’s big, it’s old and it lives under the sea—and now an international research collaboration with The University of Western Australia’s Ocean’s Institute has confirmed that an ancient seagrass holds the secrets of the oldest living organism on Earth.

Well this ain’t fun either but I came across it today and I’m stumped.
Seems to me distilled water is as pure as it gets it.
Best stuff to use in car batteries, well at least the old one’s that we needed to keep tapped up.
Why do fancy espresso machines and irons warn NOT to use distilled water?
Because it’s more corrosive. The hard water at the surface of the heating elements boils away leaving a thin, chalky skin of dried minerals that protect that metal from rapid corrosion.
Well shoot, I thought we’d found proof of Cthuthlu.
Take care,
Derek
DeadMonkey the Cthuthlu?? No wonder the bugger has become so illusive

Well that makes sense! Why didn’t I think of that… well actually I got a guess why… but won’t get into that

I still don’t understand. I thought distilling removed the minerals from the water?
Since distilled water doesn’t containt any minerals, it’s more corrosive. The minerals are the good guys. (At least that’s how I understand Occam’s explanation.)

You’re right, George.
Occam
OK, it makes sense to me.
But, now I’m trying to figure out why distilled water was recommended for them old style batteries?
Or what was it about them that kept the corrosive effect from damaging the metal plates?

1.) It’s a basic of electricity, CC. Water conducts electricity only through its ions. Distilled water has no ions and hence it cannot conduct electricity.
2.) But the Water in a lead acid battery is mixed with sulfuric acid so that it CAN conduct electricity through acidic ions (HSO4-) and hydrogen ions (H+).
3.) Tap water will work in lead-acid batteries, but the additional ions typically found in tap water muck up the nice chemical reaction lead-acid batteries are designed for so the life of the battery decreases.
Regarding corrosion, this is simply a matter of equilibrium. If water has no ions, it “wants” some, so it will rob them from things like metal.

Huh… Okay, so why is that?
Take care,
Derek
Why is what?
Traveler answered it. (What I meant was “Why are the minerals the good guys.”)
