The
Explanation of Solution
Given:
The half-reactions at which galvanic cell is based on:
The concentration of
The observed
The half-reactions at which galvanic cell is based on:
Since, the reduction potential value of copper is greater than that of vanadium so, the copper will undergo reduction and vanadium will undergo oxidation so, the half-reactions are written as:
Adding both the reactions to get the overall reactions as:
So, the overall balanced reaction for the galvanic cell is:
Now, according to Nernst equation at room temperature,
Now, the concentration of
The initial moles of
The concentration of
Substituting the values:
Now, substituting the values in equation (1) as:
Hence, the
b.
Interpretation: The value of equilibrium constant for the titration reaction needs to be calculated.
Concept Introduction: The relationship between reactants and products of a reaction in equilibrium with respect to some unit is said to be equilibrium expression. It is the expression that gives ratio between products and reactants. The expression is:
b.

Answer to Problem 132MP
Explanation of Solution
The given titration reaction is:
The expression for equilibrium constant is:
From the balanced reaction, the number of moles of reactants are same that is 1 mole for each so, the equilibrium concentration of both the reactants is same that is
At equilibrium, the number of moles of
Substituting the values:
Now, the concentration of
Substituting the values:
The values of concentrations are substitute in equation (2) as:
c.
