Excess of ammonia with sodium hypochlorite solution in the presense of gule or gelatin gives

Answer»

`NaBH_(2)`
`NH_(2)NH_(2)`
`N_(2)`
`NH_(4)Cl`

Solution :Excess of ammonia `(NH_(3))` when reacts with sodium HYPOCHLORITE solution (NaOCl) in PRESENCE of glue or GELATIN gives hydrazine `(NH_(2)*NH_(2))`. This process is known as Reschig process
`2NH_(3)+NaOC l toN_(2)H_(4)+NaCl+H_(2)O`
Addition of gelatin or glue suppress the side reaction by complexing with the metal ions and yield of hydrazine is increased.
