When I stick two electrodes in a small container of clean water, it just acts as a resistor.
When I stick two electrodes in a small container of water with iron oxide (rust), it acts like a crude capacitor (as in, connect an ohmmeter, and the reading is low at first, then increases, and if a voltage source is connected, then disconnected, a voltmeter will read some voltage across the electrodes).

I discovered this when a fault caused rusty water to be supplied. I got some of that water into a small container, along with some clean water from a bottle in another container, and decided to analyse the water (I remember that pure water doesn't conduct electricity very well, but impure water is a good conductor) by adding electrodes and connecting an ohmmeter to them. The clean water is just what you'd expect - a resistor, and nothing else. The rusty water acts like a crude capacitor.
And just to let you know, I done this so I will know when the water is safe to use (that is, I repeat this with new samples of the water until the differences between the tap water and bottle water are small). The phenomenon was discovered by accident.
My guess is that I essentially made a crude electrolytic capacitor.
Can anyone give a good explanation? This is the funniest thing I have seen since the 2004 Super Bowl halftime show.

Sounds like you did the same as the following site.

so? u made a crude battery so to speak?

gsteinb88

No...she made a capacitor. A battery sometimes acts as a capacitor, but a capacitor is not a battery.

i made a capaciter go KABOOM!! once (i guess that warning label on the box of the kit was really worth something......)

Making a boom can be easy.

1 liter pop bottle + three cups vinager + 1 tablespoon baking sode + screw the cap on fast = 1 messy kaboom.

OR

1 liter pop bottle + 1 cup crushed dry ice + 1 cup of water + screw the cap on fast = 1 loud boom.

I had a very fun chemistry teacher in High School. He would also fill a balloon full of hydrogen and light it with a match on a long stick. It was one of the examples he did out on the school's football field.

MEH! my science teacher did second one in classroom, not out side

Fantus

dang, all my science teachers just gave me notes

me likes KAboom! iv done the first one (by myself) and i thik i shorted the capaxiter what it did was: it started whisteling ::: little smoke ::::small KABOOM!!

rc fuel = highly flamible, need i say more

Yes. it is the impurities in the water that conduct electricity. A capacitor stores and discharges voltage.

mikeyp

sorta ike a battery'


right?
