Okay, if I take out H2SO4, one reaction I come up with is:
2NH2OH + Cl2 --> N2 + 2HCl + 2H2O
Or does the NH2 ion bond with Cl? This reaction is in an HCl solution, so I don't think NH2Cl would form, which would form NCl3 at low pH, correct? Am I close? BTW, I am not a student, I'm an engineer who's last chemistry class was 25 years ago.
