What happens when you combine bleach and ammonia?

When you combine bleach and ammonia, the two react to form many

toxic products, including chloramine, dichloramine, nitrogen

trichloride and hydrazine. But, if the reaction goes through all

the way, it forms non-toxic nitrogen. The equation is as


NH3+NaOCl --> NH2Cl+NaOH

NH2Cl+NaOCl --> NHCl2+NaOH

NHCl2+NaOCl --> NCl3+NaOH

NH3+NH2Cl+NaOH --> N2H4+NaCl+H2O

N2H4+2NH2Cl --> 2NH4Cl+N2

I would not recommend it unless you have proper safety

equipment, a fume hood and are doing it under supervision of a

experienced chemist.

Very bad idea! This is a potentially fatal mixture which will

release toxic vapors.

Bleach contains chlorine when it reacts with ammonia a very

toxic chloroamine is formed.
