What is produced from a reaction between Nitric acid and magnesium ribbon?
I reacted 20cm3 of 2M nitric acid with 10 cm of mg ribbon, but when it reacted the vapour wasn't white as expected.
It had a slight tinge of yellow and a stronger smell than when I reacted sulphuric with magnesium.
I think it might be nitrogen dioxide, but that is supposed to be a brown vapour, also i wasn't expecting NO2 to form.
Any help into what exactly formed and reasons for that will be greatly appreciated.
What is the product of disassociation of Sulphuric acid, does it disassociate completely?
does HSO4 act as both base and acid? in which cases can it act as a base nad when as an acid?
and does anyone know what are the dangers of NO2?

Mg + HNO3 would produce H2 gas, not NO2.
this is a simple replacement reaction in which the Mg takes the place of the H but, since it is completely able to dissociate, you are left with Mg+2 ions, NO3- ions and hydrogen gas.
H2SO4 is an acid. it has 2 dissociation products
1) H2SO4 + H2O --> HSO4-1 + H30+
2) --> H3O+ + SO4-2
nitrogen dioxide is a component of smog which, when mixed with water, can form nitrous acid which is acid rain.
