Agalvanic (voltaic) cell consists of an electrode composed of titanium in a 1.0 m titanium(ii) ion solution and a second electrode composed of tin in a 1.0 m tin(ii) ion solution, connected by a salt bridge. calculate the standard potential for this cell at 25c.

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:
