Problem

Consider these two entries from a fictional table of standard reduction potentials.

X2+ + 2e- → X(s)                  E = 1.70 V
Y2+ + 2e- → Y(s)                  E = 0.14 V

Which pair of species would react under standard conditions?

A) X 2+ and Y
B) X 2+ and Y 2+
C) X and Y
D) X and Y 2+

Solution
  • The reduction potentials (E), will tell us which entity is likely to be reduced or oxidized

  • Recall that as E increases (more positive), the more likely reduction occurs

  • According to the E given, X2+ will appear to be reduced
