Nitric acid

We have, like, own Acid name because we name ourselves, uh, our band as Acid, and Hanzor was Acidic.

Seattle, The Fallen Heroes, uh, was Nitric.

Mm-hmm.

And another guy in US named Black Acid.

Yeah, that's probably true.

Like Aquafortis.

Yeah.

And stuff like that.

The stream of gas that comes out contains about 4% of ammonia, which is condensed to a liquid by cooling and the uncombined hydrogen and nitrogen passed again through the apparatus.

The ammonia can be employed in refrigeration and other ways, but if it is desired to get the nitrogen into the form of nitric acid, it has to be oxidized by the so-called Ostwald process.

This is the reaction NH3, ammonia, plus 4O, oxygen, goes to HNO3, nitric acid, plus H2O, water.

The catalyst used to effect this combination is the metal platinum in the form of fine wire gauze since the action takes place only on the surface.

The ammonia gas is mixed with air, which supplies the oxygen, and the heated mixture runs through the platinum gauze at the rate of several yards a second.

While he was thinking, he wasn't wasting time.

What would dissolve mercury? Nitric acid.

Good old HNO3.

Fine, except that the hot lab was at the other end of the reactor where the fissure had let all the air out.

The bulkheads had dropped, and he couldn't get in, and naturally, the nitric acid would be in the lab.
