I've read online from a reliable source that the that the reason bleach and ammonia combined form chloramine fumes is because bleach deteriorates into hydrochloric acid in this process:
NaOCl → NaOH + HOCl
HOCl → HCl + O
Then the hydrochloric acid reacts with the ammonia further and produces chloramine gas.
NaOCl + 2HCl → Cl2 + NaCl + H2O
2NH3 + Cl2 → 2NH2Cl
Then, if there is leftover ammonia, the chloramine gas can combine with it to form the liquid hydrazine
2NH3 + NaOCl → N2H4 + NaCl + H2O
Liquid hydrazine, while not as highly explosive in this impure form, is still extremely toxic, and it boils and sprays hot toxic liquid.
So theoretically, since your stomach contains hydrochloric acid, wouldn't that be the same as skipping the first step of combining bleach and ammonia in your stomach? Then, depending on how much you swallowed, couldn't boiling liquid hydrazine be formed? Just wondering, don't worry, I'm not considering getting fertilizer strength ammonia and downing it. lol. I've just heard people mentioning (as a joke) drinking bleach and ammonia at the same time, and thought, why would you even need to drink the bleach, just drinking the ammonia by itself it would do the same thing, theoretically.
*Sighs* Thanks for the info, but I never mentioned swallowing bleach, a, and I didn't ask what would happen if you INHALED ammonium gas, b. I asked if you swallowed liquid ammonia. I never though about regurgitation and whatnot, but my question is more theoretical, IF the ammonia got into the stomach and stayed there, would the following reactions occur, or are there other components in play that would prevent the reactions from occurring or change them.
