What's Happening

This is discussion archived from a time before the current discussion method was installed.

LTR well, I was doing some parabomer cleanup, and looked into the Chromic Acid part, to see if I could find an actual picture of green acid.

Turns out, Chromic Acid is just the industrial term for Chromium Trioxide, a caustic compound for cleaning glassware and metals. Actual Chromic Acid is a hypothetical compound which probably does exsist, but hasn't been isolated yet. And chromium compounds can appear blue-green in color, but also other colors depending on Cr concentration. Since there was no way to comfortably put this in the entry without it turning into an, ahem, chemistry experiemnt, I cut it out.

(random passer-by) There are acids and acids. I was a chemistry major in college, long, long ago, but I still recall that chemists use three overlapping but far from identical categories of acids and bases.

Arrhenius acids create positively charged hydrogen ions when dissolved in water. Bronsted-Lowry acids are capable of donating a hydrogen ion in a chemical reaction. Lewis acids are capable of accepting an electron pair; this definition overlaps with reduction-oxidation chemistry.

The different definitions are used in different fields of chemistry.

The bit about the "phosphates" is probably confusion with the effect known as "phosphorescence" (a long-lived glow demonstrated by certain minerals and compounds)

LTR: Moved the discussion about electricity to here as I think it was informative, but outside the scope of the trope, besides, the entry itself admits that green acid isn't ficticious, just not universal.

  • I also hate to do this since I suspect it will start a huge row, but 240V is not enough to kill a human. Lightning is far higher in voltage than this as are cattle prods and electric fences. It is the associated current that kills. For those who are bothered look at what a Van De Graaf generator does.
    • This editor would like to point out that while saying that 240V doesn't kill is technically correct, it's a misnomer. What should be pointed out is that any electricity can kill, as long as you've got enough amps (current). There's even a Darwin Award for a guy who killed himself with when he stabbed himself with multimeter probes in order to measure his body's internal resistance. While the multimeter only used 9 volts, the plasma in his body was a much better conductor of electricity and thus resulted in enough amps to kill him.
    • While volts themselves don't deliver the kill, they make it a lot easier thanks to something called Ohm's Law, which states that the current is directly proportional to the voltage. Note that cattle prods, and electric fences deliver high volts in VERY short pulses that is designed NOT to kill. A 100-240 volts household socket can deliver a constant 10-20 amperes and is actually more likely to kill than cattle prods (or Van de Graaf generators) operating at thousands of volts but can only deliver milliamps of current.
    • Also, "100-250 volts of house current"? What on earth?

Nornagest: Merged a couple of overlapping Truth in Television examples.

Fluffyskunk: Can we have a JPG for this page? BMP sucks for photos, especially of Amazing Technicolor subjects.

Nymphonomicon: Has anyone noticed how a lot of shows (cartoons in particular) seem to have situations where the villian winds up holding a vial or beaker in a menacing manner in one hand and a hostage in the other? The beaker always seems to wind up being shattered and the harmful chemical becomes a puddle on the ground, which somehow makes it useless/non-threatening?
