The document discusses the application of the Nernst equation to calculate the cell potential (E°cell) in an electrochemical reaction. It provides specific values for standard potential (E°) and concentrations for products and reactants, including cadmium ions (Cd²⁺) and nickel ions (Ni²⁺). The document highlights that two electrons are transferred in the reaction.

1. We know that from Nernst Equation ,
E o cell = E o – ( 0.059 / n ) log ( [ products ] / [reactants ])
Given Eo cell = 0.17 V
Eo = 0.24 V
[products ] = [Cd 2+ ] = ?
[reactants ] = [ Ni 2+ ] = 1.0 M
N = no . of electrons transferred = 2
