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^@ C`, the standard electrode potentials are `A^(2+) //A =- 0.76 ` volts, `B^(2+) //B= +0.34 ` volts .A. A will graduall dissolveB. Water will decompose into ` H_2` and ` O_2`C. No reaction will occurD. B will deposite on A

Answer» Correct Answer - D
Since `E_(A^(+))^@ gt E_(B^(2+)//B)^@`. A has greater tendency to be oxidized.
`A+B^(2+) rarr +B`.
