Answer: The standard potential for this cell is +1.49 V at 25C.
Explanation:
As titanium has lower reduction potential, it will act as anode and tin will acts as cathode.
Using Nernst equation :
where,
F = Faraday constant = 96500 C
R = gas constant = 8.314 J/mol.K
T = room temperature =
n = number of electrons in oxidation-reduction reaction = 2
Where both are standard reduction potentials.
= standard electrode potential of the cell = 1.49 V
= emf of the cell = ?
Now put all the given values in the above equation, we get:
