<u>Answer:</u> The concentration of in the solution is
<u>Explanation:</u>
The given cell is:
Half reactions for the given cell follows:
<u>Oxidation half reaction:</u> ( × 3)
<u>Reduction half reaction:</u> ( × 2)
<u>Net reaction:</u>
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate the concentration of ion for given EMF of the cell, we use the Nernst equation, which is:
where,
= electrode potential of the cell = 1.23 V
= standard electrode potential of the cell = +1.50 V
n = number of electrons exchanged = 6
Putting values in above equation, we get:
Hence, the concentration of in the solution is
