Question

what happens when

a) Dilute sulphuric acid is poured on a copper plate?

b) Iron nails are placed in copper sulphate solution?

Write word equations of the reactions involved.
​

Answer 1

Answer:

So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. ... (b) Iron is more reactive than copper. When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green

Answer 2

a) Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. ... When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green.

b) When iron nail is dipped in Copper sulphate, it takes reaction between them and Copper sulphate changes its color from blue to light green. ... This could replace copper from CuSO4, and blue color and FeSO4 is in light green color.
