Why hydrogen is liberated when magnesium react with dilute nitric acid unlike other metals where hydrogen is not evolved?
Magnesium reacts with dilute nitric acid to form magnesium nitrate and liberate hydrogen gas because magnesium is a highly reactive metal and is able to displace hydrogen from nitric acid. Other less reactive metals do not typically react with dilute nitric acid to produce hydrogen gas.
What gas is liberated when metals react with dilute acid?
When metals react with dilute acid, hydrogen gas is liberated. This is because the reaction between the metal and the acid displaces hydrogen from the acid, resulting in the formation of hydrogen gas bubbles.
Do acids make hydrogen when they react with some metals?
Yes, acids can react with certain metals to produce hydrogen gas. The acid will donate protons to the metal, causing it to lose electrons and form metal ions. The liberated electrons then reduce hydrogen ions in the acid to produce hydrogen gas.
What gas do acids form when they react with metals?
Usually hydrogen (H2). Nitric acid usually gives NO or NO2, depending on concentration.
Do acids react with metals that are more or less active than hydrogen to form a compound of the metal and hydrogen gas?
No. Some of the less reactive metals, such as platinum, gold, silver, copper, and rhenium will not undergo this reaction. Copper and silver will react with nitric acid to produce nitrogen dioxide (NO2), a toxic brown gas. Gold and platinum will react with aqua regia, a mixture of nitric acid and hydrochloric acid, in a similar manner. Rhenium will not react with any acid.

Name some acids that react with metals?
Nitric acid reacts strongly with many metals.

What happens when matals react with acid?
when metals react with acid hydrogen gas is liberated . and salt is formed eg; 2Na+2Hcl ------ 2Nacl+H2

Usually hydrogen (H2). Nitric acid usually gives NO or NO2, depending on concentration.
Why does manganese and magnesium react with nitric acid to evolve hydrogen gas?
Manganese and magnesium react with nitric acid to evolve hydrogen gas because both metals are more reactive than hydrogen in the reactivity series. When these metals come into contact with nitric acid, they displace hydrogen from the acid, leading to the formation of metal nitrates and the release of hydrogen gas. Additionally, nitric acid can produce hydrogen gas through reduction reactions, especially in the presence of reactive metals. However, the presence of nitrogen oxides as by-products may also occur, depending on the concentration of the acid and reaction conditions.

Which metals react with nitric acid?
Aluminium is passive towards Nitric acid because Nitric acid forms a protective thin film on surface of Aluminium which protects from further reaction.
Why metals except Mg and Mn do not form hydrogen when they react with nitric acid?
The question needs an opposite answer:Most metals, except some noble ones like Pt, Au and maybe Hg or Ag, can NOT resist the oxidation power of nitric acid. This is because of the high oxidation power (potential) of nitric acid (even dilute acid is very potent).
Does hydrogen react with metals?
Hydrogen can react with metals to form metal hydrides. This reaction can occur at high temperatures or under certain conditions, and it depends on the specific metal and its reactivity with hydrogen.
Why hydrogen is not evolved when a metal react with nitric acid?
Nitric acid is a strong oxidizing agent and its molecule is unstable as compare to nitrogen oxides, on reacting with metals it gives hydrogen and oxygen both so water is produced instead of hydrogen.
