Read the following passage and answer the questions that follow :
One student was comparing the reactivity of different metals for his science project. He added iron filings in four test tubes A, B, C and D containing aqueous solutions of ZnSO4, CuSO4, FeSO4 and Al2(SO4)3.
(i) In which of the test tubes will he observe the reaction to be the most vigorous and why ?
(ii) Write a balanced equation for the reaction involved.
Solution
(i)
• Test tube B
• Iron is more reactive than copper, so iron can displace copper
from copper sulphate solution.
(ii) Fe(s) + CuSO4 (aq)→FeSO4 (aq)+Cu (s)
