Question
What is the standard potential of the Tl3+/Tl electrode ? if Eo Tl3+/Tl+ = 1.26 V, EoTl+/Tl+ = - 0.336 V
Options
A.0.728 V
B.0.118 V
C.1.728 V
D.2.728 V
Solution
Tl3+ + 2e- → Tl+; nFEo = 2 × 1.26 × F = 2.52F
Tl+ + e+ → Tl; nFEo = 1 ×(-0.336) × F = - 0.336F
Adding
Tl3+ + 3e- → Tl Eo =
= 0.728 V
Tl+ + e+ → Tl; nFEo = 1 ×(-0.336) × F = - 0.336F
Adding
Tl3+ + 3e- → Tl Eo =
= 0.728 V
