00:00Hello everyone. Welcome to this exciting lecture series on electrochemistry.
00:08Whether you are a student, a science enthusiast or someone preparing for exams like CSS, PMS
00:15or other competitive exams like UPSC or just university level chemistry courses, you are in the right place.
00:24In this series, we are going to explore the amazing world where chemistry meets electricity.
00:34So, the topics that we will learn in this series are given below.
00:39We will start with conductance. You will learn what it means when we talk about specific conductance, molar conductance and equivalent conductance.
00:49We will explore how ions move in a solution and how this ionic motion affects electrical conductivity.
00:58Next up is the Kolras law. It is a brilliant principle that helps us calculate conductance at infinite dilutions.
01:07We will also go over Hector's rule which tells us how far each ion travels during electrolysis.
01:15It is like understanding the traffic pattern for ions.
01:19Next one is the Debehical theory. This one is a little more advanced theory.
01:25We will explain the ionic atmosphere, how charged particles interact and how their activity is different from mere concentrations.
01:35This theory is essential for understanding behavior in very dilute solutions.
01:40Next one is the Fuel cells. We will understand the working of fuel cells and their construction.
01:49We will also cover different types. For example, polymer electrolyte membrane fuel cells,
01:57solid oxide fuel cells, direct methanol fuel cells, zinc air fuel cells and many more types of the fuel cells.
02:07And we will also see how hydrogen and oxygen can be used to generate clean electricity.
02:13These are not just lab experiments. They power cars, satellites and many more.
02:21Then we move into the electrolysis.
02:26Breaking compounds apart from using electricity.
02:30Different laws, for example, Faraday's laws will show us how much material goes into deposited or liberated during this process.
02:38It is all about quantitative electricity.
02:43Then we will move into the conductormetric titrations and standard electrodes.
02:50We will also look at the redoxed titrations which are used widely in the labs.
02:56You will learn about standard reference electrodes like the standard hydrogen electrode and how we can use these as benchmark in measuring electrode potentials.
03:11We will also discuss how to tell whether a redox reaction will occur on its own or need some push.
03:18We will discuss these spontaneous and non-spontaneous processes and we will also see that how electrode potentials and Gibbs free energy helps us make that prediction of their spontaneity or non-spontaneity.
03:35Next one is the electrochemical cells.
03:41We will also cover both galvanic and electrolytic cells.
03:45We will see how a battery works, how electricity flows and how these cells differ from each other based on spontaneity and direction of electron flow.
03:56We will also tackle the Nernest equations and must know formula that tells us how to calculate the actual voltage of a cell under non-standard conditions.
04:09Not everything in electrochemistry is about making energy.
04:19Sometimes it is about losing it, like in corrosion.
04:23We will explain why matter is rust, what reactions take place and how we can prevent or slow down this destructive process.
04:30This series covers even more advanced and applied topics which include, for example, over potential and concentration polarization, buffer action in electrochemistry, batteries and their types, electrochemical sensors and pH meters, applications of electrochemistry in medicine, energy and environmental science.
04:57So, whether you are revising for degree exams, competitive exams like CSS, PMS, UPSC or any other exam, it will strengthen your concept or exploring chemistry for fun.
