What is produced with nitric acid and metal?
A salt of this metal (nitrate) and hydrogen.
Why concentrated nitric acid is not used to prepare hydrogen gas?
Usually an active metal displaces hydrogen acids. But Nitric Acid is a very strong oxidizing agent i.e. it leads to addition of oxygen to another substancevery quickly . Thus, when hydrogen is formed due to the addition of a metal to nitric acid, it oxidises hydrogen into water. That is why concentrated nitric acid is not used in the preparation of hydrogen gas.
Why hydrogen is liberated when magnesium react with dilute nitric acid unlike other metals where hydrogen is not evolved?
This may due to Magnesium metal has high reactivity and concentration of nitric acid is dilute, thus magnesium reacts with H+ in water/ in nitric acid to give hydrogen
When metal reacts with nitric acid hydrogen is not produced why?
It is so because nitric acid is a very strong oxidising agent and as according to oxidation, it says loss of hydrogen is very important.... Thus, hydrogen is not produced. :)
Name the gas produced when nitric acid is added to copper metal?
hydrogen

What metal cannot displace hydrogen from dilute acid?
Silver

Why most of the transition metal not displace hydrogen in acid?
because some metals are less reactive than hydrogen.

Name the gas produced when nitric acid is added to copper metal?
hydrogen
Why nitric acid does not liberate hydrogen gas with most metals?
It is because HNO3 is a strong oxidising agent.So as soon as H2 is formed in the reaction between a metal and dilute nitric acid oxidises this hydrogen to water.
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.
What are the products obtained when metal reacts with dill nitric acid?
What the product of an interaction between a metal and diluted nitric acid is depends on which metal is used. Most metals in this combination result in a metal salt and a hydrogen. Silver, however, creates three products when combined with nitric acid: nitrogen monoxide, silver nitrate and water.
Where does the gas come from when metal reacts with acid?
No. Copper will not react with most acids. It will react with nitric acid to produce nitrogen dioxide. Gold and platinum will not react with nitric acid but will react with aqua regia, a mixture of hydrochloric and nitric acids to produce nitrogen dioxide and some nitric oxide. Rhenium does not react with acid at all.
Which metal will displace hydrogen from an acid?
zinc magnesium aluminum iron nickel tin lead
