What happens when nitric acid reacts with metal?

Metals react with acids to form salt and hydrogen gas, but with nitric acid, most metals react to form salt and nitrogen oxide as it is a very strong oxidising agent.

Why nitric acid does not react with most of metals?

And Nitric acid is a string oxidizing agent. So as soon as hydrogen gas is formed in the reaction between a metal and nitric acid, the nitric acid oxidizes hydrogen gas to water and itself get reduced to any of nitrogen oxides. Thus nitric acid does not release hydrogen gas upon reaction with metals.

Why hydrogen gas is not evolved when metals react with nitric acid Name the two metals which reacts with dilute nitric acid?

Hydrogen gas is not evolved when a metal reacts with nitric acid. It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2). But magnesium (Mg) and manganese (Mn) react with very dilute HNO3 to evolve H2 gas.

Which of the following metals reacts with nitric acid and produces hydrogen gas?

Magnesium (Mg) and manganese (Mn) are the only metals that react with very dilute nitric acid ( 1\% nitric acid) to liberate hydrogen gas.

Which metals do not react with nitric acid?

Some precious metals, such as pure gold and platinum-group metals do not react with nitric acid, though pure gold does react with aqua regia, a mixture of concentrated nitric acid and hydrochloric acid.

Which reaction does not produce hydrogen gas?

The second reaction that is between zinc and concentrated sulfuric acid, it does not evolve hydrogen gas because Concentrated sulphuric acid and zinc react to form Zinc sulfate, water, and sulfur dioxide. The concentrated sulphuric acid acts as an oxidizing agent.

Which of the following metals reacts with nitric acid and produces hydrogen gas a sodium B magnesium C Aluminium D iron?

Magnesium react with cold and dilute nitric acid to form hydrogen.

Which of the following metal react with base to release hydrogen gas?

Answer: Zinc and Aluminium reacts with both acid and base and also release hydrogen.

Why nitric acid does not liberate hydrogen on reaction with zinc?

Nitric acid does not liberate hydrogen in reaction with zinc because nitric acid is a strong oxidising agent and it oxidises hydrogen produced to water nd itself gets reduced to any of the nitrogen oxides ( N2O , NO , NO2).

Which of the following acids do not liberate hydrogen when reacts on most metals?

The correct answer is Cu. Copper (Cu) does not liberate H2 when it reacts with acid. Cu is least reactive than Hydrogen.

Which metal does not produce hydrogen gas when added to acid?

Simply, in order to produce hydrogen from acid, a metal has to be above from the hydrogen in the electrochemical series(metal has to react more vigorously or more reactive). So the metal like gold, silver, copper ,platinum etc don’t produce hydrogen with acids as they can’t able to replace the hydrogen in the reaction.
