a) Which of the following reactions are possible if sodium is more reactive than aluminum, iron, and lead? Reaction I: Sodium + Aluminum chloride →Sodium chloride + Aluminum Reaction II: Sodium chloride + Iron → Iron chloride + Sodium Reaction III: Sodium + Lead chloride → Sodium chloride + lead b) Justify your choice

Answer 1

Explanation:

Reaction I is possible bcoz sodium will displace aluminium.

Reaction II is not possible bcoz iron will.not displace sodium.

Reaction III is also possible bcoz sodium will displace lead.

hope it helps u...

Answer 2

Answer: Reaction I and III are possible.

Explanation: A metal (sodium, here) can only displace another metal from its salt solution if it is placed higher in the reactivity series. As sodium is more reactive than iron, aluminium and lead, it can displace them from their salt solution in reactions I and III whereas in reaction II, no reaction will take place because lead cannot displace sodium as its less reactive.
