When black copper oxide is added to dilute sulphuric acid what colour is the soloution at the end?
Blue cupric sulfate solution
Added:
Chemical formulas:
- CuO, Cu(II)-oxide, cupric oxide (monocopper oxide), black
- Cu2O, Cu(I)-oxide, cuprous oxide (dicopper oxide), red
- sulfuric acid, H2SO4
CuO + H2SO4 --> CuSO4 + H2O , cupric sulfate, blue solution
Cu2O (red) also reacts with dilute sulfuric acid forming CuSO4 by:
Cu2O + 2 H2SO4 --> CuSO4 + H2O + H2, cupric sulfate, blue solution
What else can I help you with?
What occurs when copper reacts with dilute sulphuric acid?
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
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 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 colour phenol red indicator in dilute sulphuric acid?
below pH 6.8above pH 8.26.8 yellow↔8.2 purple
How does copper reacts with acid when copper is below hydrogen in reactivity series?
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.
What happens when copper is reacted with dilute sulfuric acid?
Copper does not react with dilute Sulphuric acid.
What happens when copper oxide reacts with dilute sulphuric acid?
Copper Oxide reacts with Sulphuric acid to form Copper Sulphate and Water.
What occurs when copper reacts with dilute sulphuric acid?
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
What happens when dilute sulphuric acid-is poured on copper plate?
Sulfuric acid react with copper.
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 is formed when copper is added to dilute sulphuric acid?
cu + H2so4 --->cuso4+2H two molecules of hydrogen evolves........
What is the symbol of dilute sulphuric acid?
H2SO4(dilute)
Is dilute sulphuric acid compound?
No. It is a mixture of sulphuric acid and water.
What would be the colour of the solution when copper oxide and dilute hydrochloric acids are mixed?
Blue
