Question

which of the following metals liberate hydrogen with dilute HNO3
1)Cu
2)Zn
3)Ma
4)Mg​

Answer 1

Answer:

Copper, silver, gold and platinum being less reactive than hydrogen cannot displace hydrogen from acids.

Metals that are more reactive than hydrogen can displace hydrogen from acids. These metals include sodium, potassium, lead and zinc.

Answer 2

Explanation:

how ever metals like magnesium and manganese still produce hydrogen gas but with very dilute nitric acid only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate hydrogen gas
