Please answer Q27 and tell why the other options are incorrect.
Dear Student,
The decreasing order of reactivity series of metal is as follows:
Li > K > Ca > Na > Mg > Al > Zn > Fe > Ni > Sn > Pb > Cu > Ag > Au > Pt
Since Mg is most reactive among these metals, hence it displaces the other metal ions from its salt solution.
Option C is correct
