Do all metal liberate hydrogen gas from dilute acids.?
Answer:
Active metals such as Sodium, potassium etc and moderately active metals such as magnesium, aluminium, zinc, iron etc reacts with dilute acids ( except for HNO3 ) to produce H2 gas. HNO3, being oxidizing agent, oxidises the H2 so produced into H20.
Poorly active metals such as platinum, silver, gold etc do not liberate H2 on reacting with dilute acids.
