how to determine this??? How is this displacement thing decided?
Please find below the solution to the asked query:
A metal of stronger reducing power displaces another metal of weaker reducing power from its salt.
When the electrochemical series is seen, we get the order of increasing reducing power of the given metals is:
Cu< Fe< zn< Al <Mg
Thus Mg can displace Al from its salt solution, but Al cannot displace Mg
Thus the order in which the given metals displace each other from the solution of their salts is given as:
Mg>Al> Zn> Fe>Cu
