Question: 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 ${{A}^{2+}}/A=-0.76\,volts,\,{{B}^{2+}}/B=+0.34\,volts$

1) $A$ will gradually dissolve

2) $B$ will deposit on $A$

3) No reaction will occur

4) Water will decompose into ${{H}_{2}}$ and ${{O}_{2}}$
