Mg react with HNO3 more than 5 ways....

products of the reactions are changing according to HNO3's concentration....

I'm giving 5 ways of reaction here.....

1) Mg(s) + 2HNO3(dil - 2%) ------> Mg(NO3)2 (aq)+ H2(g)

2) 4Mg(s) + 10HNO3(dil) ------> 4Mg(NO3)2(aq) + NH4NO3 + 3H2O

3) 4Mg(s) + 10HNO3 ------> 4Mg(NO3)2(aq) + N2O(g) + 5H2O

( in the stage of Number 2), can get NH4NO3 as a product. but it is not stable...

by increasing concentration it will divide into ------> N2O +2H2O )

4) 3Mg(s) + 8HNO3(50%) ------> 3Mg(NO3)2(aq) + 2NO(g) + 4H2O

5) Mg + 4HNO3(extreme cons.) ------> Mg(NO3)2 +2NO2(g) + 2H2O
