The happiness of successfully completing playlist is on the another level ✨❤️🌈

Ek ghante ki new journey jo hello bachao se suru hogi or all the best par khatam hogi. 😁😁😁😁

Kohlrausch's law starts from 42:03

Alakh sir is the only teacher whose 1 hour class I can attend without getting bored !!

physis wallah ka vedio dekh dala to life ginalala 👌👌👌👌👌👌👏👏😃😃like for physics wallah

Batch of 2025 here

Is there anyone seeing now the old videos of alakh sir. This man proved that old videos are gold😊

2023-24 batch drop some love guis this chapter was finished in our school long back but watching it again with alakh sirs explanation gives 100 times more clarity to every thing

The happiness of completing full playlist is different🌈💫

Sir ki ayu itni saal bar jaya 👇

Bestestttttt teacher I have ever seen🙌🏻🙌🏻🙌🏻🙌🏻👌👌👌👌👌.,,,,

Au=gold ❌ Alakh sir = gold ❤

Best teacher in my life,, with fully dedication

When this guy said “ hum sabka pyarasa channel-PW” , we all felt that.🖤

Electrochemistry Done.. Gonna Start Chemical Kinetics After 3 Days.👍🏻 All The Best Guys 🙂👍🏻

Watching in quarantine days cant understand at zoom live class . He is very good at explaining

U never say it's my beautiful sa channel...always...."it's ur beautiful sa channel".. aapki inhi chhoti chhoti baaton se aapke liye respect or jyda ho jti h 😍😍

This great man is changing our perspective to deal with physics.... There is no 'term' in dictionary which can describe his greatness and influence.💐💐

Brilliant explanation! I was so confused in electrochemistry some weeks ago, and here I am, solving nearly every problem in the chapter.

Hellloooo sir Video banate rahe, all the very best 🤘😅😅

He even tended to demote his own website saying that *They indeed have notes but, taking notes down yourself will be way better*, salute the honesty of this man

Nobody can find a teacher like u by searching in the whole world There are a very few people like u; godmade and very unique and special

Sir please corrosions aur batteries waale jo topics bach gaye hai unhe bhi upload kar dijiye ☺

When my mind says one shot dekhle, pr fir mann kheta hai feel ke liye prrna hai toh alakh sir 🥰😊

only RU-vidr who doesn't even talk about liking the videos and subscribing

It feels great to complete this playlist...😊

After learning concepts from PW, when I attend the same lecture in my school my reaction is:- 'Accha humko sikhariya hain"... 😁😁😁

At 1:10:36 do you think sir has made a mistake in finding equivalent conductivity of al2(so4)3??? He had forgot to multiply Al by 2 and So4 by 3 Pls reply!!!

2020 me interview me sbke muh se saflta ka raj alakh pandey nikalega jb jee ke results aayenge

Completing a playlist hits different 😊

54:10 the exact same question has come in neet2021 thank you sir!

Completing a playlist without any doubt hits hard 😜❤

after purchasing the batch,i m here studying with the old lectures of our legend🫀 WE LOVE YOU SIR🥺♥️🖇️💎💫

46:19 . When he said " Ions ke lie ye wala lambda and electrolyte lie lie ulta V wala lambda".I was freezed coz I wrote the simple lambda so many times. And then I was swiping the pages back and singing in my mind that " It is the time to cut it! Cut it! Cut it! And cut it!" 😂😂

Finally completed my ELECTROCHEMISTRY journey with you sir Maakasam aisa explain koi nahi kar saktha ❤️❤️

Finally Ch 3 .... Electrochemistry done.... All 9 videos are Very very helpful ❤...... Thank you so much Sir 😊

Physics wallah is a great help for students Thank you ALAKH SIR for all your efforts

One of the LEGEND in explaining

I have subscribed the batch but yeh sir is like a god to me . The way he explains it couldn't be compared to any one . Its phenomenal. Really respect u very much

Should'nt we multiply 3 and 2 in 1:04:35

Really enjoyed and learned all the concepts of electrochemistry through your lectures sir🤞🙏😍 Thankss alot sir God bless uu always🙏🤞😍❣️❣️😍

Thanks Physics Wallah for uploading Electrochemistry.

There are 10 days left to my 12 boards exams but still i am watching his 9 lectures of 1 hr each instead of watching 1 shot video. THAT IS THE MAGIC OF ALAKH PANDEY.

Feeling so happy after completing the greatest ever masterpiece lectures of Electrochemistry

1:03:08 Sir I think second last question ka answer (9a+4b)×1/6hoga Equivalent molar conductivity of Ca^2+=a/2 Equivalent molar conductivity of Po4^3-=b/3 Equivalent molar conductivity of Ca3(po4)2= 3×a/2 + 2× b/3 = (9a+4b)×1/6 ans...

finally the whole series completed part by part in 4 days thank u sir

Sir I have doubt in question no. 4 1:04:08 the coefficient of calcium ion and phosphate ion should be 3 and 2 respectively as the number of ionasable ion of cation and anion is 3 and 2. In question no. 5(ii) 1:10:32 the coefficient of aluminium ion and sulphate ion should be 2 and 3 respectively as the no. of ionasable ion of cation and anion are 2 and 3 respectively. Sir please reply this doubt. Love from West Bengal.❤️

Legends has its saying that people are still waiting for next lecture...... 🧓

42:00 se start hota ha KOHLRAUSCH's law.. :-)

Sir you are doing a very good job by helping everyone and may god always keep you happy hit like whoever agrees

In the second part of last ques ......I think the answer should be 575 S cm^2 eq-1

@Physicswallah sir electrochemistry ki remaining videos bhi upload kr dijiye!!🙏🙏🙏

where are other videos

sir why did u say that most of the part of electrochem has been completed is any part left?

sir pl upload the remaining lectures of electrochemistry

I love this channel best teacher literally.

Satisfaction after completing full series of this chapter 😊 Sir you make difficult chapters/topics so easy to learn and understand ❤❤

Sometimes we can't understand what our teacher teaches in our school but your teaching methods is awesome and we get clarity from your videos. Thank you sir. Thank you so much. A lot of love and respect from odisha 🙏🙏🙏

12:00 to 20:00 for revision of variation of conductivity(spe,eq,molar) on dilution p.s this is fr my revision..U guys can follow as well!!

Sir aapki wajah se mere 10 class me 98 percent aaye h Thnku a lot sir 😘😘

Sir congrats for 1.2M subscribers.l pray you will deserve 2M subscribers very very soon 😂😂😂😭😉 love from me

honestly , how u solved the first question made me rember the numericals of Hess Law...

Battery kaha h🥺

I search many new videos but alakh sir even best

59:35 can also be done as (3)-1/2(2)+1/2(1)

Satisfaction that u get after completing the chapter from alakh sir....😀😀

Thank you sir i become more happy when you upload new video for us

Me studying from lakya jee 2025 same concept but alakh sir is legend ❤❤❤❤❤❤

Dislikes are from jealous commerce students who wished to hv teacher like sir Alakh Pandey a.k.a Physics Wallah

Who else is annoyed of unacademy ads 😩

Jo log chahte h sir ...ko dheroo aur lakho blessings mile ❤❤👇

1:10:32 👉 Al^+3 ko 2 and so4^-3 ko 3 se multiply hoga ya nahi?

46:58 - 47:25 :- The molar conductivity at infinite dilution for strong or weak electrolyte is equals to the sum of the molar conductivity of ionisable cations and anions with each cation and anion terms multiplied by the number of that cations and anions which are ionized by that electrolyte.

You are legend🏅🏅🏅🏅🏅🏅

Anyone here for revision 😂

Finally I did it 🫠❤

You never say " it's my beautiful sa channel " in fact you always say "this is our beautiful sa channel physics wallah " we all love you sir,,❤☺🙏🙏

Sir some topics is missing from NCERT batteries, fuel cells and corrosion

Best part when he sings while erasing the board gives me more strength nd seems topic very easy😅❤

Sir apke teachers bahut ache hai jinhone app ko bahut acha paraya

Good Evening Sir, Im very thankful to you for your extreme support and help. Aap iss channel ki help se bohot logo ki help kar rahe hain jo ki bohot badi baat hai. Mai ek proper coaching center mai padhta hu jaha teacher bolte hain ki its there exclusive study material but mujhe wahi sab aapki videos mai free mai padhne ko milta hai and im very thankful for it. Sir its from bottom of my heart that you please continue with your extraordinary work and help students who are not financially strong enough to afford costly tuition fee. A very Thankyou dear sir, Your Student, Aditya Mittal

we really appreciate your efforts sir, thank you so much!

Sir, aap bol rahe ho ki kuch concepts bache h. Toh, Lecture 10 kaha h ?

Sir in the last question I think Al2(So4)3 will be ionised as 2Al3+ + 3(So4)2-.Therefore the answer should be different

I always call kohlraush law ....-Cockroach law 😅😅😅

Sir we are blessed that we have a teacher like you !!! Who can explain us in such a easy way that we didn't even realise that the topic was tough!!! Love you alot sir🌸🌸💜

Sir answer of last question ,part 2 is 575 Scm^2mol^-1.

Complete the chapter feeling another level 😂😂

Finally completed the whole series in 5 days... Thank you Sir for your efforts and love for ourselves... ♥️🥰✨♥️

38:16 😂😂yes sir very relatable Lizard fight

Start - helllooooo bacchooooooooo....... End- all thheeeee very best.❤️

I just truly don't have words sir. Hats off to you. You don't leave LITERALLY ANY SINGLE DOUBT IN OUR MINDS!!! Pata hain, class me sab meko "question bank" kehte hain, par ye koi nahi sochta ki kuch important kadi hain, jo teachers chhod dete hain. Aapse seekhne ke baad na toh koi kadi adhoori chhooti, aur na hi koi doubt aaya. Aur do pal ke liye aaya bhi, toh teesre pal aapne hi vo samajh liya, aur khud hi solve kar diya. Today, when this chapter has ended, i can confidently say ki "Ab main electrochemistry ka koi bhi problem solve kar sakti hoon!" Thanks a lot sir, lots of blessings with you. Krishna ji se aapki khushion ke liye pray karti hoon!❤

Sir pls kabhi mat kaha karo ki aapki writing Achi nahi hai. Your writing is so good that we can understand it very easily. Sir you teach so good. I never liked chemistry but because of you I started liking and understanding it.

53:30 NEET 2021 question with same values🤩. This proves that Neet is asking jee mains pyqs directly

thank you sir you are really great I am from lakshya i have confusion in this topic but now everything is clear because of you

congratulations on your completing the chapter

In 50:25 instead of using your method. Can we use variables to make it a equation and then solve it? Cuz it makes the finding more easy
