What else can I help you with?
What color change is there when you add black copper oxide to sulfuric acid?
When you add black copper oxide to sulfuric acid, the solution turns blue because copper sulfate was formed and it is a colored compound.
What is observed when copper oxide is added into excess dilute sulphuric acid?
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.
What happens if hydrochloric acid is added to copper 2 oxide?
When hydrochloric acid is added to copper (II) oxide, a reaction takes place where copper (II) chloride and water are formed. The equation for this reaction is: CuO + 2HCl → CuCl2 + H2O.
What happens if you add hydrocloric acid to copper oxide?
When hydrochloric acid is added to copper oxide, a chemical reaction occurs where the acid reacts with the oxide to form copper chloride and water. The balanced equation for this reaction is: CuO(s) + 2HCl(aq) -> CuCl2(aq) + H2O(l) The copper oxide is dissolved in the acid to form a blue-green solution of copper chloride.
What happens when sulphuric acid and black copper oxide heated gently?
When sulfuric acid reacts with black copper oxide and is heated gently, the copper oxide is reduced to copper and water is formed. The reaction can be represented as follows: CuO (s) + H2SO4 (aq) → Cu (s) + H2O (l) + SO2 (g)

What happens when you add excess copper oxide to dilute sulphuric acid?
When excess copper oxide is added to dilute sulfuric acid, the excess copper oxide will react with the acid to form copper sulfate and water. The reaction will continue until all the copper oxide is used up. This is known as a limiting reactant situation, where one reactant is completely consumed before the other.
Is copper oxide an acid?
No. Copper oxide has no acid-base properties.
Why was the copper II oxide added in excess to dilute sulfuric acid to form the soluble salt copper II sulphate?
Copper II oxide was added in excess to ensure that all the sulfuric acid reacted, forming water and copper II sulfate. This method helps to avoid any excess sulfuric acid remaining in the solution, ensuring that all copper II oxide reacts completely to form the desired copper II sulfate salt.
What happens when dilute sulphuric acid is added to copper oxide?
When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.
What is the word equation for the reaction between copper oxide and sulfuric acid?
Copper oxide reacts with sulfuric acid to form copper sulfate and water. The word equation is: Copper oxide + sulfuric acid → copper sulfate + water.
Write a word equation for copper oxide?
The chemical formula for copper oxide is CuO.
Which salt is produced when copper oxide reacts with hydrchloric acid?
Copper chloride is produced when copper oxide reacts with hydrochloric acid.
