For the cell prepared from electrode A and B: Electrode A:Cr_2O_7^(2-)|Cr^(3+),E_(red)^@ =+1.33 V and Electrode B:Fe^(3+) / Fe^(2+),E_(red)^@=0.77 V. Which of the following statements are correct :

Given the standard electrode potentials, K^(+) // K = - 2.93 V, Ag^(2+) //Ag = 0.80 V Hg^(2+) //Hg = 0.79 V , Mg^(2+) //Mg = - 2.37 V, Cr^(3+) //Cr = - 0.74 V Arrange these metals in their increasing order of reducing power.

E^@ for Fe^(2+) +2e rarrFe is -0.44 volt and E^@ for Zn^(2+) +2e rarrZn is -0.76 volt thus:

What does the negative sign in the expression E_(Zn^(2+) //Zn)^(@) = -0.76V mean ?

Consider the standard potential of the following cells, (i) Mg^(2+) +2e rarr Mg,E^@=-2.37V (ii) Zn^(2+) + 2erarrZn,E^@ =-0.76V (iii) Ni^(2+) +2e rarrNi,E^@=-0.25V (iv) Fe^(3+) + 3e rarrFe, E_0=-0.04 V find the strongest reducing agent :
