What happens when copper reacts with dilute and concentrated HNO3?
Solution Concentration If the nitric acid is dilute, the copper will be oxidized to form copper nitrate with nitric oxide as a byproduct. If the solution is concentrated, the copper will be oxidized to form copper nitrate with nitrogen dioxide as a byproduct.
Which gas is formed when copper reacts with dilute acid?
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.
What happens when copper reacts with concentrated hydrochloric acid?
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.
Does hno3 react with copper?
Hint: Copper is an inaccessible metal and does not react with dilute acid under normal conditions. However, it reacts with nitric acid. Nitric acid is an oxidizing agent and the reaction is not a normal acid + metal reaction. The products are oxides of nitrogen instead of hydrogen.
Does copper react with HNO3?
Copper is an unreactive metal and doesn’t react in normal circumstances with dilute acids. However, it does react with nitric acid.
Does copper react with hno3?
Does copper react with concentrated Sulphuric acid?
Copper is a metal which has a high value of reduction potential and negative value of oxidation potential. So copper does not react with dilute sulphuric acid but reacts with concentrated sulphuric acid. When copper is heated with concentrated sulphuric acid. Concentrated sulphuric acid is an oxidising agent .
What happens when copper oxide reacts with concentrated sulphuric acid?
Copper (II) oxide reacts with sulfuric acid to create water and copper (II) sulfate. This reaction could be classified as a double displacement reaction or a neutralization reaction.
