Consider the following reduction processes: $\mathrm{Zn}^{2+}+2 \mathrm{e}^{-} \square \mathrm{Zn}(\mathrm{s}) ; \mathrm{E}^{\circ}=-0.76 \mathrm{~V}$ $\mathrm{Ca}^{2+}+2 \mathrm{e}^{-} \square \mathrm{Ca}(\mathrm{s}) ; \mathrm{E}^{\circ}=-2.87 \mathrm{~V}$ $\mathrm{Mg}^{2+}+2 \mathrm{e}^{-} \square \mathrm{Mg}(\mathrm{s}) ; \mathrm{E}^{\circ}=-2.36 \mathrm{~V}$ $\mathrm{Ni}^{2+}+2 \mathrm{e}^{-} \square \mathrm{Ni}(\mathrm{s}) ; \mathrm{E}^{\circ}=-0.25 \mathrm{~V}$ The reducing power of the metals increases in the order: (a) $\mathrm{Ca}<\mathrm{Zn}<\mathrm{Mg}<\mathrm{Ni}$ (b) $\mathrm{Ni}<\mathrm{Zn}<\mathrm{Mg}<\mathrm{Ca}$ (c) $\mathrm{Zn}<\mathrm{Mg}<\mathrm{Ni}<\mathrm{Ca}$ (d) $\mathrm{Ca}<\mathrm{Mg}<\mathrm{Zn}<\mathrm{Ni}$

Topic 3 : Redox Reactions and Electrode
Standard reduction electrode potentials of three metals A, B and $C$ are $+0.5 \mathrm{~V},-3.0 \mathrm{~V}$ and $-1.2 \mathrm{~V}$ respectively. The reducing power of these metals are (a) $\mathrm{B}>\mathrm{C}>\mathrm{A}$ (b) $A>B>C$ (c) $C>B>A$ (d) $\mathrm{A}>\mathrm{C}>\mathrm{B}$
Given $\mathrm{A}^{+} / \mathrm{A} \longrightarrow+0.34 \mathrm{~V}$ $\mathrm{B}^{+} / \mathrm{B} \longrightarrow-1.66 \mathrm{~V}$ $\mathbf{C}^{+} ; \mathbf{C} \longrightarrow+0.76 \mathrm{~V}$ $\mathrm{D}^{+} / \mathrm{D} \longrightarrow-0.28 \mathrm{~V}$ The most reactive metal which displaces other metals from their salt solution is (1) $\mathrm{C}$ (2) D (3) $\mathrm{B}$ (4) $\Lambda$
