Question

name one metal which displaces from its salt solution and one metal which cannot displace zinc from its salt solution

Answer 1

hey friend
aluminium (Al) can displace zinc from its salt solution.
copper (Cu) cannot displace zimc from its salt solution

hope it will help

Answer 2

According to reactivitiy series...
Zinc is highly reactive element than copper. So when Zinc metal or rod dip into a copper sulphate solution, Displacement reaction takes place....Zinc being highly reactive displaces copper from its salt solution...and product so formed are zincsulphate and copper deposited over the zinc rod...

Niw if we take zincsulphate solution and dip copper rod into the solution, no reaction takes place. Becuase Copper is least reactive metal than zinc..

so Copper is the metal which does not displace zinc from its salt solution...
