Hydrogen gas is not liberated when the following metal is added to dil $HCl$.

$K,$ $Ca,$ and $Li$ metals may be arranged in the increasing order of their standard electrode potentials as

Give the cell potential formula for the Daniell cell and the Copper-Silver cell.

Given:
$E^o_{Cr^{3+}/Cr} = -0.74 \ V$,$E^o_{MnO_4^-/Mn^{2+}} = 1.51 \ V$
$E^o_{Cr_2O_7^{2-}/Cr^{3+}} = 1.33 \ V$,$E^o_{Cl_2/Cl^{-}} = 1.36 \ V$
Based on the data given above,the strongest oxidising agent will be:

For the following cell,the standard potential of the copper electrode is $0.337 \ V$ and the standard cell potential is $0.463 \ V$ for the reaction $Cu|Cu^{2+}(1 \ M)||Ag^{+}(1 \ M)|Ag$. What is the standard potential of the silver electrode (in $V$)?

If $Cu^{+} + e^- \to Cu$ ; $E^o = X_1$ and $Cu^{2+} + 2e^- \to Cu$ ; $E^o = X_2$,then the value of $E^o$ for $Cu^{2+} + e^- \to Cu^{+}$ will be
