Question
Which of the following listed metall can displace zine from its salt Bolution? Justify with equation. Cu, Pb, Mg Ag
Solution
The reactivity series of metals is an empirical tool used to predict the reactivity of metals with water and acids in replacement reactions. A metal can displace a less reactive metal from its salt solution.
The reactivity series from highest to lowest is: Mg > Zn > Pb > Cu > Ag
So, from the given metals, only Magnesium (Mg) can displace Zinc (Zn) from its salt solution because it is more reactive.
The equation for this reaction would be:
Mg(s) + ZnSO4(aq) -> MgSO4(aq) + Zn(s)
This equation shows that Magnesium displaces Zinc from Zinc Sulphate solution to form Magnesium Sulphate and Zinc.
