Which gas is liberated when copper reacts with dilute nitric acid?

Which gas is liberated when copper reacts with dilute nitric acid?

nitrogen dioxide
When copper is reacted with cold, dilute nitric acid it yields copper nitrate, water, and nitric oxide. And again it undergoes a reaction with air, which is nitric acid reacts with oxygen and gives nitrogen dioxide. Nitrogen dioxide is a poisonous brown gas with an irritating odor. So the answer is nitrogen dioxide.

Which gas is liberated when dilute nitric acid react with zinc?

N2O gas is liberated when zinc reacts with dilute HNO 3 .

What happens when Cu and Zn reacts with Dil hno3?

When the copper and zinc react with dilute nitric acid, HYDROGEN gas is liberated.

Which gas is liberated when copper reacts with concentrated hydrochloric acid?

hydrogen
Copper reacts with hydrochloric acid and liberates hydrogen from the solution of dilute hydrochloric acid.

What happens when Cu reacts with hno3?

Talking about the reaction between copper and nitric acid, copper is oxidized by concentrated nitric acid to produce \[C{u^{2 + }}\] ions. The nitric acid is reduced to form nitrogen dioxide which is a poisonous brown gas with an irritating odour. Also, Cupric nitrate, \[Cu{(N{O_3})_2}\] is formed in this reaction.

Is nitric acid a volatile acid?

Nitric acid is a more volatile acid than sulphuric acid is displaced by sulphuric acid from metal nitrates.

Does zinc react with dilute nitric acid?

In this reaction, the hydrogen atom of nitric acid is replaced by zinc. It is due to reactivity or electrochemical series. The oxidation potential of zinc is higher than that of hydrogen. So, the oxidation state of zinc changes from 0 to +2.

When zinc reacts with dilute nitric acid nitrous oxide is produced what mass of the gas is evolved by treating 325 g zinc with excess of nitric acid?

Zinc reacts with dilute nitric acid producing N2O in accordance with the following equation. 4Zn + 10HNO3 = 4Zn(NO3)2 +N2O+5H2O. The atomic mass of Zn is 65.38u and the molecular weight of N2O is 44. So 65.38×4 g or 261.52 g of Zn gives 44 g of N2O.

Which of the following gases is are liberated during the action of HNO3 on metals?

When a metal reacts with nitric acid, no hydrogen gas is produced. It’s because HNO3 is a strong oxidizer.

What happens when copper reacts with hydrochloric?

Yes, it is obvious that copper will not react with hydrochloric acid for the simple reason it’s below hydrogen in the reactivity series. So, copper cannot replace the hydrogen in HCl to form CuCl2 . Hence, when copper (Cu) reacts with hydrochloric acid (HCl) there will be no reaction.

Which gas is released when Cu reacts with concentrated h2so4?

sulphur dioxide gas
Copper reacts with hot and concentrated sulphuric acid to form copper sulphate, sulphur dioxide gas and water.

What happens when copper and zinc react with dilute nitric acid?

Reaction with zinc leads to nitrogen-containing species that are more reduced than with copper. This correlates with the greater reducing power of zinc. It is more electropositive than copper. When the copper and zinc react with dilute nitric acid, HYDROGEN gas is liberated. When metal reacts with acid HYDROGEN gas is produced.

Why does zinc displace hydrogen from dilute hydrochloric acid?

Zinc is above hydrogen whereas copper is below hydrogen in the activity series of metals. That is why zinc displaces hydrogen from dilute hydrochloric acid, while copper does not. Zn+HCl→ZnC12​+H2​Cu+HCl→ No reaction ​

What happens when PB metal reacts with dilute HNO3?

When Pb metal reacts with dilute HNO3, a redox reaction takes place, and Pb (NO3)2 + NO + H2O is formed. Nitric oxide (NO) can react further with oxygen in the air to form nitrogen dioxide (NO2). Nitric acid is an acid, but it also is a powerful oxidizing agent.
