What happen when copper oxide reacts with dilute 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.
How does copper oxide dissolve in dilute sulfuric acid?
Method
- place some sulfuric acid in a beaker and warm it in a water bath.
- add a spatula of copper(II) oxide powder to the acid and stir with a glass rod.
- continue adding copper(II) oxide powder until it is in excess.
- filter the mixture to remove the excess copper(II) oxide.
What happens when you add water to copper oxide?
Copper ( I) Oxide can react with water as the oxygen is present in the water and make Copper (II) Hydroxide. Through the chemical reaction between hydrogen chloride and copper (I) oxide, Copper (I) Chloride is formed.
Is cuso4 soluble in water?

Does copper react with 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.
Why does copper not react with dilute sulphuric acid?
Copper does not react with dilute sulphuric acid. This is because copper is lower in reactivity series than hydrogen. Copper has higher reduction potential than that of hydrogen. Thus, copper cannot displace hydrogen from the non-oxidising acid.
Why CuSO4 is soluble in water?
Copper Sulfate can dissolve in water because water is a polar solvent. The polarity of water leads to the positive copper ions being attracted to the oxygen atoms of water with a partial negative charge and the sulfate ions being attracted to the hydrogen atoms of water that have a partial positive charge.
What happens when you mix sulfuric acid with copper oxide?
In this experiment, students react an insoluble metal oxide with a dilute acid to form a soluble salt. By reacting copper (II) oxide, a black solid, with colourless dilute sulfuric acid, they produce copper (II) sulfate with a characteristic blue colour.
Which is the concentrated form of sulphuric acid?
The concentrated form of sulphuric acid is a dense, oily, and corrosive. The other compound copper oxide is a compound that is formed when two elements copper and oxygen react with each other. Its formula is CuO.
Why does Copper not react with 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. READ: Is 1/3 of the Senate up for election every two years?
What happens when copper oxide is dissolved in chlorine?
The chlorine-containing complex is formed if copper(I) oxide is dissolved in concentrated hydrochloric acid. You can think of this happening in two stages.
