Mixing bleach and ammonia does not make a super cleaner (idea) by anglopwr

There are several ways household ammonia and bleach can react. All of them are dangerous.

Reaction type 1: Ammonia directly reacts with bleach to form hydrazine (N₂H₄), which, in addition to being extremely poisonous, can burn even in the absence of air! It explodes on contact with rust!

2NH₃ + NaOCl -----> N₂H₄ + NaCl + H₂O

Reaction type 2: Bleach hydrolyzes into sodium hydroxide and hypochlorous acid, which in turn decompose into chlorine gas and nascent oxygen (both poisonous). The chlorine gas in turn reacts with the ammonia to form chloramines, also very poisonous.

NaOCl -----> NaOH + HOCl
HOCl ---> HCl + O (monatomic oxygen)
NaOCl + 2HCl -----> Cl₂ + NaCl + H₂O
2NH3 + Cl₂ -------> 2NH2Cl (chloramine)
4NH3 + 2Cl₂ ------> 2NHCl₂ (dichloramine)
6NH3 + 3Cl₂ ------> NCl₃ (trichloramine or nitrogen trichloride)
