When a rod of metal A is dipped in an aqueous solution of metal B (concentration of `B^(2+)` ion being 1M) at `25^(@)C`, the standard electrode potentials are `A^(2+)//A=-0.76`volts, `B^(2+)//B=+0.34` voltsA. A will gradually dissolveB. B will deposit on AC. No reaction will occurD. Water wil decompose into `H_(2) and O_(2)` |

Answer» Correct Answer - B Since `E_(A^(2+)//A)^(o) lt E_(B^(2+)//B)^(o)`. A has greater tendency to be oxidized. `A+B^(2+)toA^(2+)+B`. |
