As + HNO3 (consentrated) -> H3AsNO4 + NO2 + H2O
The Attempt at a Solution
I tried doing the electron equation:
As (0) - 1 electron = As (1+) | 1
N (5+) + 1 electron = N (4+) | 1
I dont know if this is right. (The last 2 numbers are supposed to represent the numbers which should go in the equation before those elements.)
Think the oxydation level is supposed to change, but the sides dont balance out. What am I doing wrong? I just cant get this out of my head anymore.
Thanks in advance,
