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 color effervescense when sulfuric acid and copper oxide are mixed?
What is the colour of the solution formed when copper oxide is dissolved in dilute sulphuric acid? it turns blue!!!!!!!!!!!!!!!!!!!
What occurs when copper reacts with dilute sulphuric acid?
no reaction will take place because copper does not react with dilute sulphuric acid, it will only react with hot and concentrated sulphuric acid.
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?
Copper sulphate + water
Is Mercury dilute sulphuric acid?
Uno palabra no. mercury is mercury dilute sulphuric acid is just that dilute sulphuric acid.
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.

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.
Method for manufacturing copper sulphate?
There are various method for manufacturing copper sulphate commercially. it can be manufactured by the action of sulphuric acid on copper in the presence of air/O2. reacting copper with dilute sulphuric acid in the presence of strong oxidising agents like HNO3. By converting copper into copper oxide and dissolution of oxide into dilute sulphuric acid. once we get liquid copper sulphate solution from reaction then the normal operations are filtration , concentration, crystallisation, separation & drying of crystals
What is the reaction between copper and sulfuric acid?
No, there is no reaction between copper & H2SO4 because according to reactivity series of metal hydrogen is more reactive than copper. Hence copper does not displace hydrogen from sulphuric acid..
