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.
Why most metal do not displace hydrogen from nitric acid?
Most metals do not displace hydrogen from nitric acid because nitric acid is a strong oxidizing agent that prefers to undergo reduction itself rather than allow the metal to displace hydrogen. Nitric acid can oxidize the metal directly, forming metal ions and nitrogen oxides, instead of being displaced by the metal to form hydrogen gas.
What metals cannot displace hydrogen gas from a dilute acid?
all those metals which are present below Hydrogen in the reactivity series like Ag , Cu , Au , Pt ,etc. ^^ He is incorrect. All metals, one or another, will react with some acids to produce Hydrogen Gas. -He mentioned Copper and Silver. Silver and Copper will react with Nitric Acid giving off Hydrogen and NitroDioxide Gas. He mentioned Gold and Platinum. Gold and Platinum will react with Aqua Regia (A mixture of Hydrogen Chloride and Nitric Acid) giving off Nitric Oxide, Nitrogen Dioxide, and Hydrogen gas. All metals will react with FluoroAntimonic Acid, Xenic Acid, or any other super acid to give off hydrogen gas and other gases as well.
What is the reaction between metals and dilute nitric acid?
Metals react with dilute nitric acid to form metal nitrates, hydrogen gas, and water. The nitric acid oxidizes the metal to form the metal nitrate, releasing hydrogen gas in the process. The reaction is typically vigorous and can produce nitrogen dioxide gas as a byproduct.
Why is nitric acid in the dilute form not used in the laboratory preparation of hydrogen from metals?
It is because nitric acid is a strong oxidising agent (because it decomposes to yield nascent oxygen as:2HNO3 →2NO2 + H2O + [O])and it oxidises the hydrogen formed to water.Only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate Hydrogen gas.

Which of the following metals reacts with dilute nitric acid?
Silver is the metal that reacts with dilute nitric acid to form silver nitrate, nitrogen dioxide gas, and water.
Why nitric acid does not liberate hydrogen gas with most metals?
Nitric acid is a strong oxidizing agent that can readily oxidize hydrogen gas to water, meaning it cannot act as a reducing agent to liberate hydrogen gas from most metals. Instead, it will oxidize the metal and produce nitrogen oxides or nitrate salts.
What gas is evolved when dilute nitric acid is added to Zinc?
When dilute nitric acid is added to zinc, the gas evolved is nitrogen dioxide (NO2) along with water and zinc nitrate.
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).
What happens when aluminium reacts with dilute nitric acid?
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
Why hydrogen gas is not liberated when metals react with nitric acid?
Nitric acid is a strong oxidizing agent that can oxidize hydrogen gas to water instead of being reduced itself to release hydrogen gas. As a result, metals do not liberate hydrogen gas when they react with nitric acid.
What gas is formed when dilute nitric acid reacting with magnesium?
Magnesium will react with nitric acid and most other acids to produce hydrogen gas.
