Vedclass · Answer

(A) The chemical activity of a metal is related to its standard reduction potential $(E^o)$. $A$ more negative reduction potential indicates a stronger reducing agent and higher chemical activity.The standard reduction potentials are:$Na^{+} + e^{-} 	o Na$,$E^o = -2.71 \ V$$Mg^{2+} + 2e^{-} 	o Mg$,$E^o = -2.37 \ V$$Cu^{2+} + 2e^{-} 	o Cu$,$E^o = +0.34 \ V$Comparing the values: $-2.71 \ V Therefore,the order of increasing chemical activity is $Cu < Mg < Na$.

The correct order of increasing chemical activity for the given metals is:
