Solution: Consider the half reaction Ag+ ( aq ) + e-  →  Ag( s ).What is the value of Ered when log[Ag+] = 0?

Problem

Consider the half reaction Ag+ ( aq ) + e-  →  Ag( s ).
A graph has log of Ag+ concentration on the x-axis and E subscript red on the y-axis (both unscaled).  Line 1 increases linearly, line 2 is horizontal midway up the y-axis, and line 3 decreases linearly. There is a vertical dashed line where all three intersect.

What is the value of Ered when log[Ag+] = 0?
