	If the reduction potential is more, then
	The ${{E}^{0}}$ for half cells $Fe/F{{e}^{2+}}$ and $Cu/C{{u}^{2+}}$ are $– 0.44 V$ and $+ 0.32 V$ respectively. Then
	The reaction $Z{{n}^{2+}}+2{{e}^{-}}\to Zn$ has a standard potential of – 0.76 V. This means
	The standard reduction potential for $L{{i}^{+}}/Li$; $Z{{n}^{2+}}/Zn$; ${{H}^{+}}/{{H}_{2}}$ and $A{{g}^{+}}/Ag$ is – 3.05, – 0.762, 0.00 and + 0.80 V. Which of the following has highest reducing capacity
	When a rod of metal $A$ is dipped in an aqueous solution of metal $B$ (concentration of ${{B}^{2+}}$ ion being 1 M) at ${{25}^{o}}C$, the standard electrode potentials are ${{A}^{2+}}/A=-0.76\,volts,\,{{B}^{2+}}/B=+0.34\,volts$
	The standard oxidation potential of zinc and silver in water at $298 K$ are $Zn\,(s)\to Z{{n}^{2+}}+2{{e}^{-}};\,E=0.76\,V$ $Ag\,(s)\to A{{g}^{+}}+{{e}^{-}};\,E=-0.80\,V$ Which of the following reactions actually take place
	A gas X at 1 atm is bubbled through a solution containing a mixture of $1\,M\,{{Y}^{-}}$ and $1\,M\,{{Z}^{-}}$ at ${{25}^{o}}C$. If the order of reduction potential of Z > Y > X
	Which of the following statements are correct
	Given that $E_{A{{g}^{+}}/Ag}^{0}=+0.80\,V$ and $E_{Z{{n}^{2+}}/Zn}^{0}=-0.76\,V$, which of the following is correct
	$E_{N{{a}^{+}}/Na(s)}^{0}=-2.71\,V$, $E_{M{{g}^{2+}}/Mg(s)}^{0}=-2.37\,V$, $E_{C{{r}^{3+}}/Cr(s)}^{0}=-0.41\,V$. Based on this data, state which of the following is the weakest reducing agent
