Solid Nitric Acid ?
I've heard from a teacher that although ionic compounds in their solid crystalline state do not conduct electricity, solid nitric acid is an
exception.
In its solid state, it undergoes following reversible reaction :
HNO3---------> H+ + NO3-
HNO3 + H+ ------------>H2NO3+
Is it correct that solid nitric acid conducts electricity? Or is it just the vice versa?

You know the person who told you this, so why do you ask us? Ask your teacher for the reference.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

How do those reactions lead to electricity conduction?
Solid state conductors are metals, semiconductors, certain special polymers, certain materials (tin-indium oxide).
Whatever the material is, there needs to be a charge carrier.

Sorry, that teacher was just a stranger. I have no acquaintance with him. Now can you help me clarify this problem ?
@vmelkon
Are you sure ?

I don't know if nitric acid will conduct electricity (my Google-Fu is weak, as I haven't found any statements one way or the other), but if those
equations represent solid-state reactions, then it is plausible that the substance would conduct, as hydrogen ions could be passed from one nitric
acid molecule to another, resulting in net movement of positive charge along the sample.

I am studying this right now, and it appears that a materials "edge" effect can conduct, depending on it's design.
Graphene in "armchair" configuration , molybdenum, and unhooked benzene rings all conduct (apparently) phonons without using a carrier, and actually
by moving down the asymmetrical chain, produce current that can be harvested.
not a lot of info being released, as the researchers are chasing thermoelectric applications.
Lots of interesting research going on right now... and most of it does show increases when hydrogen is present, even from bacterial sources. lots of
papers released this week on nanogold and iron with hydrogen supplied from archea and other primitive bacterias are fun.

Same question and debate elsewhere;
http://www.chemicalforums.com/index.php?topic=62571.0
I doubt that solid 100% nitric acid can conduct.
If there was some water there so it formed a solid solution I think it might conduct.

I have never read anything specifically about solid nitric acid being a conductor, but it would not completely surprise me if it were indeed true. A
small number of ionic solids can conduct ions. Lithium nitride, for example, can conduct lithium ions through the crystal lattice. Solid bismuth oxide
can conduct oxygen ions at elevated temperatures. Rubidium silver iodide conducts silver ions at room temperature. I wonder if some sort of transistor
is possible utilizing P- and N-type solid ion conductors.
I'm not saying let's go kill all the stupid people...I'm just saying lets remove all the warning labels and let the problem sort itself out.

a little off topic, but still sort of relevant: you should never blindly trust your teacher, you should her all the shit my chem teacher crams out!
CCl4=chloroform, stomach acid is mainly HNO3,...!
all above information is intellectual property of Pyro.  |

I get the feeling that Pyro knows that, but his so-called chem teacher doesn't.

I guess that no one is sure whether solid nitric acid does conduct electricity or not. I think that majority says that it does not. Thanks..
Any more comments are welcomed

Re-solid nitric acid
Hiii,
I found these references:
http://www.ncbi.nlm.nih.gov/pubmed/23090634
http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=69...
https://www.stanford.edu/group/efmh/jacobson/Articles/Others...
Can anyone tell what these references say and derive the conclusion??

First paper: Solid nitric acid will protonate the carbonyl groups without water present. Not particularly useful for what you're trying to find out
except that it indicates a significant acidic character in solid nitric acid.
Second paper: A way to find conductivity in solids was found using acoustics (sound). Could be more useful if you could recreate the apparatus and
test the nitric acid yourself.
Third paper: Page not found.
