Question

when iron is added to CuSO4 solution copper is displaced and iron form FeSo4 in solution .Will Fe be displaced pb from pbso4 solution and Zn from ZnSo4 solution​

Answer 1

Answer:

1. Fe+CuSO4=FeSO4+Cu
2. Fe+PbSO4=FeSO4+Pb
3. Fe+ZnSO4=no reaction because Fe is less reactive than Zn

Explanation:

metal activity series decreasing order is

K,Na,Ca,Mg,Al,Zn,Fe,Pb,Cu,Hg,Ag,Au,Pt

Answer 2

Scandium and Germanium
