Question

Decide if a reaction will take place when lead is placed in a solution of magnesium sulfate. If you think there will be a reaction, write the word equation for it and if you think there will be no reaction, explain the reason. *

Answer 1

No, there will be no reaction as Lead lies much below magnesium in the reactivity series of metals.

Only a more electropositive metal can displace a less electropositive metal from its salt.

Lead is much less electropositive than magnesium, so it cannot displace magnesium metal from its salt in the solution state.

Answer 2

Answer:

The order of reactivity is magnesium > iron > lead. This is because magnesium could displace lead and iron, iron could only displace lead, but lead could not displace magnesium or iron.
