Question

what will happen if: magnesium is treated with very dilute nitric acid

Answer 1

Like many metals magnesium reacts with dilute acids to produce hydrogen plus the magnesium salt of the acid. e.g.

Mg + 2HNO3 ----> Mg(NO3)2 +H2

However, if concentrated nitric acid is used magnesium reacts violently to produce oxides of nitrogen (NO & NO2), as the nitric acid is reduced by the magnesium, which is a strong reducing agent;-

Mg + 2HNO3 ---> MgNO3 + NO2 + H2O

Answer 2

When Mg reacts with nitric acid (HNO3)then,
Magnesium nitrate produces and some amount of Hydrogen gas elaborate.....

Reaction =》
Mg+HNO3 ----------->Mg (NO3)2+H2(g)



Hope u understand.......
