Consider the following standard reduction potentials:- `{:(Fe^(+)+2e^(-)hArrFe,,,E^(@) =- 0.41V),(Ag^(+)+e^(-)hArrAg,,,E^(+)=0.80V),(O_(2)+2H_(2)O+4e^(-)hArr4OH^(-),,,E^(@)=0.40V):}` What would happens if a block of silver metal is connected to a buried iron pipe via a wire:-A. The silver metal would corrode, a current would be produced in the wire, and `O_(2)` would be reduced on the surface of the iron pipe.B. The silver metal would corrode, a current would be produced in the wire, and `Fe^(2+)` would be reduced on the surface of the iron pipe.C. The iron pipe would corrode, a current would be produced in the wire, and `Ag^(+)` would be reduced on the surface of the silver metal.D. The iron pipe would corrode, no current would be produced in the wire, and `O_(2)` would be reduced on the surface of the iron pipe. |
