Answer:
When metal reacts with
nitric acid (HNO3), hydrogen gas is not evolved. This is because HNO3
is a strong oxidizing agent. It oxidizes H2 produced to water and is
itself reduced to any of the oxides of nitrogen (N2O, NO or NO2).
For example,
3Cu(s) +
8HNO3(aq)
3Cu(NO3)2(aq)
+ 2NO(g) + 4H2O(l)
