Let me remind, A redox (reduction-oxidation) reaction is a chemical process where one substance loses electrons (oxidation) and another gains electrons (reduction). It's like a transfer of electric charges, where one becomes more positive and the other more negative. Thank you ma'am 😊😊😊

Very funny 😒

English translation of the video ! (Part 1) Note - some parts of the video are paraphrased as ma'am was repeating some words or sentences for emphasis before abruptly cutting off to another sentence or was repeating stuff. Anything in brackets is me telling you what happened in short rather than it being word to word. Introduction part of electrochemistry. 0:54 -> When you focus on the name 'electrochemistry', in it, 'electro' must have come from 'electricity' and chemistry which basically stands for 'chemical reactions'. This means we're going to be studying the relation between electricity and chemical reactions in electrochemistry. Now we can say, "electrochemistry is the study of electricity and how it relates to chemical reactions." All in all, we're going to be studying two concepts in this whole chapter. Firstly, we're going to be learning about how we can generate electricity from a chemical reaction. Secondly, we're going to be learning about how we can use electricity to do a chemical reaction. Which means we can be talking about chemical energy to electrical energy or vice versa. Now the base of these things happening, that is chemical to electrical and electrical to chemical, will be redox reactions. We'll be seeing that the reactions happening within them, are what kind of reactions ? Redox reactions. 2:17 -> (Ma'am telling people who don't know what redox reactions are to go watch the 11th class chemistry video on the topic.) 2:28 -> (Ma'am continues with the chapter) In electrochemistry, we'll now be talking about generating electricity from a chemical reaction. Now here, in this type of situation, what reaction will we be taking about ? Spontaneous reactions. In the other situation, we'll use electricity to conduct a chemical reaction so during this we'll be talking about non-spontaneous reactions. Understood ? No ? (Does the thumb hand gesture) We'll understand them both properly. 3:06 -> Now kids, when we talk about spontaneous reactions, (sudden cut off to an explanation) Spontaneous, self motivated ! Someone who is motivated by themselves, this type of reaction, which means "Capable of proceeding in a given direction with no external energy being needed." (Repeats the same thing in Hindi and then compares the reaction to a self motivated studious kid. Further elaborates, a kid like that would require no external energy like scoldings, beatings, fear of exam, greed, etc to study.) Now where do we study spontaneous reactions ? (Reminds us of the two concepts again.) When we generate electricity from chemical reactions. Now here the chemical reactions happen on their own, no force. Here we talk about spontaneous reactions, reactions which occur on their own. During the reaction, the energy we get is used to generate electricity. 4:22 -> (Starts with the self motivated example.) Now not every kid is self motivated, there are some devil kids who want absolutely nothing to do with studying. These kids are mentally scarred (exaggerated by me just cuz, sorry !) with thoughts of failing class and no promotion, given greed and other times scolding, beating etc etc. These all behave like an external push or an external energy. The kid sadly starts studying. (...I start doing stuff like translating 2+ hour long videos instead I guess, lol) Just like this, non-spontaneous reactions don't happen on their own but to make them happen in a particular direction we provide an external energy. Now we'll talk about non-spontaneous reactions where things will be using electricity to make a chemical reaction occur. Since they don't occur on their own, we give them an external push and there we'll be taking about non-spontaneous reactions. 5:48 -> (Gives an example from day to day life.) The example - If we keep water on the top of a mountain then the water will start flowing downwards or down the hill on its own but if we were to keep the water at the base of the mountain will it go 'toi toi toi toi' up the mountain on its own ? No. It can go up with the help of a motor. In fact, in our houses the water reaches the eighth or ninth floor using a motor. Here we have provided an external energy due to which the process is happening. This is non-spontaneous. (Repeats the two concepts again.) 6:58 or 6:59 -> Is it important to study electrochemistry ? Absolutely YES ! One small thing is a battery. Now if we were to look around without the battery a lot of things would not work like say a watch, a mobile phone, a calculator, a laptop, a camera, an electric car or even toys. (Tells us that 90% of her daughter's toys consist of batteries) It is not that only a battery is the use of electrochemistry but the battery is a very important application. There are many more applications as well like electroplating. 7:45 -> Now what is electroplating ? Have you ever noticed in your house, gold plated jewelry. Jewelry which are not made of gold but appearance wise look like it. This because they have been layered or plated with gold. There are some utensils that look like they are made of silver but are actually plated with it. You must have noticed many times, chrome plated handles, the handles contain a layer of chrome. What are all these electroplating. Meaning, on one metal we deposit a layering of another metal and this is also a concept from electrochemistry. 8:25 - 8:35 -> (Thinks now that we know its uses we'll be more interested in the chapter.) 8:36 -> Now in electrochemistry, we talk about two types of cells. Which two cells ? 1. Electrochemical cells 2. Electrolytic cells What are these two cells ? (Repeats the two concepts again.) Electrochemical cells convert chemical energy to electrical energy. Also called Galvanic or voltaic cell named after the scientists, Volta(Alessandro Volta) and Galvani(Luigi Galvani). The elctrolytic cell does the exact opposite, it converts electrical energy to chemical energy. 9:21 -> (Tells us to keep our basics clear.) Elctrochemistry's basics lie in redox reactions. 9:38 - 9: 45 -> (Reminder to watch 11th class video if someone doesn't know redox.) (Update - currently on hiatus.)

Dear Roshni Mam, Mam actually l am a law aspirant , but still took science according to my parent's opinion : l Initially, starting from class 11th l found everything so much tough, as all the coaching centres were closed due to lockdown that l can't explain my helplessness in words : ( But, then I found this channel providing free education and your one shot videos really helped me to cover whole syllabus in a very less time and making my concepts crystal clear! And I am preparing for my boards only from this channel : D Really Mam Really, I am very thankful to you from bottom of my heart and I don't know many number of times I ought to thank you! Thank you so much Mam : ) Omisha

Thank you so much, ma'am...!like really, I can't express how grateful I am, truly! To be honest, I completely relied on your Channel for my exam preparations and I was no longer afraid of my exams but sometime later, I couldn't find some lessons, some chapters...I got nervous and from many people's suggestions, I tried other platforms...and I actually thought for a few days that they may help but I come back here again because truly ma'am, there is a difference in this aura that you give, we can see your dedication, we can see that you are truly trying to help us get a better understanding of the concept and not just for scoring marks in exams. while many other platforms made me simply nervous and scared, your videos are really comforting and instill all the concepts into us in a perfectly crystal clear manner. I love your teaching style! Thank you so much, ma'am

Great work ma'am. You are the only one who explains in such a good that it fits to our mind and our concepts become very clear

those so-called famous teachers are just famous by names but don't even know how to teach a student because student is studying it for first time if you are not teaching for the first time i hate those kind of teachers but i feel she is the greatest teacher ever thank you soooo much mam

Concept hua crystal clear... Whole year I avoided this chapter but finally I dare to this...just becoz of u mam...thanku soo much ❤️💕
