Question

Illustration the reducing property of ammonia with example

Answer 1

Answer:

Ammonia is an active reducing agent. It has this property because of presence nitrogen atoms that have an oxidation number "-3". Restorative properties of nitrogen are observed at combustion of ammonia in air. The most stable oxidation number of nitrogen is 0, the result of this reaction is free nitrogen.

Hope this is useful for you.

Answer 2

"Answer:

These following reactions demonstrate reducing power of ammonia:

1) 2NH3 + 3 CuO ---> 3 Cu + 3 H2O+ N2(g)

2) 2NH3 + 3 PbO(amphoteric oxide) ---> 3 Pb + 3 H2O + N2(g)

3) NH3 + Cl2 ---> 3 HCl + NCl3

4) 8 NH3 + 3 Cl2 ----> 6NH4Cl + N2     (excess ammonia)
