Solving the Standard Potential of NO in Alkaline Medium

In summary, the standard reduction potential of NO converted to N2O in an acid medium is 1.59V, and its standard potential in an alkaline medium at 298K is unknown. By reversing the equation for the standard potential in an alkaline medium and adding it to the equation for the standard potential in an acid medium, we can calculate the standard potential in an alkaline medium to be approximately 0.764V. However, this calculation may be incorrect and further assistance is needed from the chemical forums community.

Homework Statement


in acid medium the standard reduction potential of NO converted to N2O is 1.59V .its standard potential in alkaline meduim at 298k would be?

Homework Equations


a)2NO+2H ---> N2O +H20 E=1.59
b)2NO + H2O ---->N2O + 2OH- E=x
c)2H2O---->2H+ + 2OH- E=0.826 (calculated, correct and verified)

The Attempt at a Solution


Reversing b) we get E= -x
adding a and reversed b, we get reversed c. Therefore 1.59-x=-0.826, so x should be 1.59+0.826 but this is incorrect. Where am I wrong? any help would be appreciated.

I just became a member on chemical forums. It seems to have a more active chemistry community than PF but I wonder why their interface isn't as uncluttered and intuitive as here
