 · An iron knife kept dipped in a blue copper sulphate solution turns the blue solution light green. Why? [2] Ans. As we know iron is more reactive than copper. So, it displaces Cu from CuSO4 solution and forms ferrous sulphate which is of Light Green Colour. CuSO4 (aq)+Fe (s) → FeSO4(aq) + Cu(s) Blue colour light green colour A copper coin is kept in a solution of silver nitrate for some ...

Does Copper React With Acid?

Does Copper React With Acid?

 · Copper does not react with dilute sulphuric acid because of its positive reduction potential. It cannot replace hydrogen atoms in dilute sulphuric acid. But if the sulphuric acid is hot and concentrated, then it can undergo reduction. As concentrated H2SO4 is an oxidizing agent for copper. Therefore, if concentrated sulphuric acid is heated with the copper metal, acid undergoes reduction .

What colour change would you observe during this reaction?

 · When it reacts with sulphuric acid, it produces a cyanblue colored chemical which is known as copper sulphate. The blue color is due to the formation of soluble salt. The copper and sulphate ions dissociate as the copper sulphate gets dissolved in water. Although there is no change in the effect, however, the nature of the split between t2g and eg orbitals in this new complex is such that it absorbs .

The Copper Cycle

The Copper Cycle

O+ ions are neutralized, additional OH– ions react with the Cu2+ ion to form Cu(OH) 2 precipitate. Once all the Cu2+ –ions have reacted, no more precipitate forms. Adding more OH ions makes the solution basic, so it can turn red litmus paper blue. Figure 2 on the next page shows the stepwise reaction of Cu2+ with NaOH.

Oxidation and Reduction

If we turn off the flame, and blow H 2 gas over the hot metal surface, the black CuO that formed on the surface of the metal is slowly converted back to copper metal. In the course of this reaction, CuO is reduced to copper metal. Thus, H 2 is the reducing agent in this reaction, and CuO .
