When an ion‑selective electrode for x+ was immersed in 0.0482 m xcl, the measured potential was 0.0460 v . what is the concentration of x+ when the potential is 0.0610 v ? assume that the electrode follows the nernst equation, the temperature is at 25 °c, and that the activity coefficient of x+ is 1.

Answer : The concentration of is 0.0861 M

Explanation :

First we have to calculate the standard electrode potential of the cell.

Using Nernest 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 = 1

= standard electrode potential of the cell = ?

= emf of the cell = 0.0460 V

[X] = concentration = 0.0482 M

Now put all the given values in the above equation, we get:

Now we have to calculate the concentration of when the potential is 0.0610 V.

Using Nernest equation :

Therefore, the concentration of is 0.0861 M
