Answer:
The potential wrt. calomel is 1.254 V
Explanation:
Given:
Potential wrt. silver chloride
V
Potential wrt. saturated silver chloride
V
Potential wrt. SCE
V
Now potential wrt. hydrogen is given by,
V
And we find for potential wrt. calomel,
potential wrt. hydrogen + potential wrt. SEC

V
Therefore, the potential wrt. calomel is 1.254 V
