The e value of copper is positive
WebThe E ∘ value for the M n 3 + ∣ M n 2 + couple is much more positive than that for C r 3 + ∣ C r 2 + couple or F e 3 + ∣ F e 2 + couple because M n 3 + ion receiving an electron gets d-subshell half-filled which is highly stable, while in case of F e 3 +, d − subshell is already half-filled, so it does not receive electron easily.
