A student took a solution of copper sulphate in a beaker and put a clean iron nail into it and left it for about an hour. i) What changes do you expect? ii) Are these changes chemical in nature? iii) Write a word equation for the chemical change.
Answers
According to the question,
It is given that a student took a solution of Copper Sulphate in a beaker and also, put a clean iron nail into it and left it about an hour!!
⠀⠀━━━━━━━━━━━━━
I) What changes do you expect ?
When an iron nail is immersed in the solution of CuSO4 then that iron nail displaces Cu from the solution of CuSO4 as iron is more reactive than Cu respectively!
Therefore, CuSO4 solution colour changes from blue to pale green [or simply green].
⠀⠀━━━━━━━━━━━━━
II) Are these changes chemical in nature ?
Yes, the changes are chemical in nature as new components , iron sulphate and copper are formed.
- Iron sulphate = Green in colour
- Copper = Brown in colour
⠀⠀━━━━━━━━━━━━━
III) Write a word equation for the chemical change .
Where,
- Copper sulphate = CuSO4 (Blue)
- Iron = Fe
- Iron sulphate = FeSO4 (Green)
- Copper = Cu (Brown)

III) Write a word equation for the chemical change .
\begin{gathered}\sf \: Copper \: Sulphate + Iron \longrightarrow Iron \: sulphate + Copper \\ \end{gathered}
CopperSulphate+Iron⟶Ironsulphate+Copper
Where,
Copper sulphate = CuSO4 (Blue)
Iron = Fe
Iron sulphate = FeSO4 (Green)
Copper = Cu (Brown)
