CHEM-1100 Chapter 19 Lecture Notes
Introduction Electrochemistry deals with interconversion of electrical and chemical energy Many chemical changes can be clearly related to the electrons that move from one species to another Often this electron exchange can be captured to do electrical work external to the chemical system (storage battery fuel cell) |

Objectives
After studying this Unit, you will be able to describe an electrochemical cell and differentiate between galvanic and electrolytic cells; apply Nernst equation for calculating the emf of galvanic cell and define standard potential of the cell; derive relation between standard potential of the cell, Gibbs energy of cell reaction and its equilibrium
3.3 Nernst Equation
We have assumed in the previous section that the concentration of all the species involved in the electrode reaction is unity. This need not be always true. Nernst showed that for the electrode reaction: Mn+(aq) + ne–→ M(s) the electrode potential at any concentration measured with respect to standard hydrogen electrode can be represented by: ) = (
E ( E [M]
n + /M n + ) – ln M M /M nF [M n+ ] but concentration of solid M is taken as unity and we have ncert.nic.in
3.4.1 Measurement of the Conductivity of Ionic Solutions
We know that accurate measurement of an unknown resistance can be performed on a Wheatstone bridge. However, for measuring the resistance of an ionic solution we face two problems. Firstly, passing direct current (DC) changes the composition of the solution. Secondly, a solution cannot be connected to the bridge like a metallic wire or other solid
Quantitative Aspects of Electrolysis
Michael Faraday was the first scientist who described the quantitative aspects of electrolysis. Now Faraday’s laws also flow from what has been discussed earlier. ncert.nic.in
3.5.1 Products of Electrolysis
Products of electrolysis depend on the nature of material being electrolysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gold), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reac
3.6 Batteries
Any battery (actually it may have one or more than one cell connected in series) or cell that we use as a source of electrical energy is basically a galvanic cell where the chemical energy of the redox reaction is converted into electrical energy. However, for a battery to be of practical use it should be reasonably light, compact and its voltage s
The Hydrogen Economy
At present the main source of energy that is driving our economy is fossil fuels such as coal, oil and gas. As more people on the planet aspire to improve their standard of living, their energy requirement will increase. In fact, the per capita consumption of energy used is a measure of development. Of course, it is assumed that energy is used for
Summary
An electrochemical cell consists of two metallic electrodes dipping in electrolytic solution(s). Thus an important component of the electrochemical cell is the ionic conductor or electrolyte. Electrochemical cells are of two types. In galvanic cell, the chemical energy of a spontaneous redox reaction is converted into electrical work, whereas in an

The conductivity, κ, of an electrolytic solution depends on the concentration of the electrolyte, nature of solvent and temperature. Molar conductivity, Ëm, is defined by = κ/c where c is
