Interpretation:
The cell voltage at each volumes of added
Concept Introduction:-
Cell Voltage:
Cell voltage is the difference between cathode potential and anode potential.
The unreacted concentration in the solution is determined by
Ion-selective electrode:
An ion-selective electrode (ISE) best known as a specific ion electrode (SIE), is a sensor (or transducer) that transforms the activity of a specific ion dissolved in a solution into an electrical potential.
Ion-selective electrode obeys following equation.
Explanation of Solution
