Don't worry sir sab accha hoga. Poorness kabhi insaan ko aage badhane se nahi rok sakti. You sometimes think that today approx 6lakhs students are learning from you. It is very great thing you have. Thanks for your support.

Sir jo last question kie h video mei! Usme no. Of moles of (oh) 10^(-3) hona chahiye na?
sir,
your lecture is really superb
but my request is to take class in English medium also
this will be useful for non hindi students like me
expecting positive response from you
Thank you
I can understand the hard work put by Sir ,
Because continuously teaching for 2 hours soo interactively without the presence of students , is not a joke ,
Really sir is a great man

Kaise aya

answer of 55:00 question - Hope it helped , as it took me 5min to write it!
Ka=α
2×10^-4 =0.5c
α=2×10 ^-2
[H^+ ]=c×α
∴[H ^+ ]=0.5×2×10 ^−2
=10 ^
−2
pH=−log[H^+]
=−log[10 ^−2]
=2×(log10)
=2
Tnx
Thank u it helped me ❤
thanks bro
No it's super easy it didn't helped me try to solve good question
Ye bro it really helped me your minutes worth it
U have surely brought a revolution on UA-cam and provided an undefinable support to self studies!! My God bless you
Salute to you sir. Your videos quite literally changed the way I view science. Physics used to be a burden at first, now I actually like studying physics. Just bcz of you!!! Same with this chapter and many other chapters in chem. I was so scared of ionic equilibrium for months. Even thermodynamics seemed easier than this. But after watching your vid on the topic I was hooked!! You explain the concepts so well!! No wonder you have so many of us students as die hard fans. You truly deserve a Bharat Ratna. Pranam. 🙏🙏
thermodynamics is easier than this bro way too easy
@@CSiddhrthKathairia That's what I was also thinking! Thermodynamics ke concepts easy hai and kafi had tak formula based hai!

@@shreyanshsingh7328
Same here
My teacher completed in approximately 20 days😊
Here is the answer of Homework
Given,
Ka= 2×10^-4
M= 0.5(where we are taking1/2)
Formula is a^2=Ka/c
a= √2×10^-4÷0.5
=√2×10^-4 ×2/1(here we are taking 0.5 in 1/2 form)
=√4×10^-4
a =2×10^-2
Now,
[H+]= C ×a
= 0.5×2×10^-2
= 10^-2
Ph comes out =2
Thank you 😊💞
Yes correct ❤
Thanks vi
Yes , my answer is correct thank you ❤

Friday-20 May 2022 (11:26 PM)
At 1:39:16 Sir has forgotten to multiply the no. Of moles of (OH)‐ ions by 2 as Ba(OH)² is a diacidic base. Thus the answer should be 3.
Hope this helps get rid of any confusion 😊😊
Happy Learning Everyone.
No, that's not how it is done....in that question we directly got the total moles of OH- .....so there was no need to multiply it with stoic coefficient
@@SilverGate007
(3.29 am 25/06/2022)
1:28:10 look there sir considered that with multipling 2 for [H+]
So it also would be the last one by multiplying 2 . And ans would be 3.4~~3
@@amirhamza449 cause in 1:28:10 - conc was given and not the Ph … and in 1:39 - Ph was given so you do not have to multiply it by 2 …
Agar Ph se moles nikalenge to x factor already consider karke hi aaya hoga Ph ..
In a nutshell - Ph k time pe not to consider the stoic coefficients
Yes bro
If it's dibasic can we apply that formula
Our Sir is putting much more effort than whole educational department in the country for students
I personally feel that sir should be awarded with Bharat Ratna AWARD
Who all agree with me

Answers of 55:49 is 2 i hope that it can help you
55:47 option b is correct
HF = H+ + F-
C. 0. 0
C-Calpha. Caplha. Calpha
Ka = c× alpha ka square
Alpha = √ka/c
Alpha=√3×10 power minus 4/0.5
Alpha= 2× 10 pr power minus 2
H= c× alpha
H= 0.5× 2 × 10pe power minus 2
H= 10 pe power minus 2
Then
Ph= -log[H]
Ph= - log[10 pe power minus 2]
Ph =2
there is a mistake in ur solution the ka isnt 3times 10 to negetive 4 its 2 times 10 to negative 4

I also got the same answer but is it possible for a weak acid to have pH=2
Sir in last question, Ba(OH)² is there so there will be 2OH which will be dissociated so we need to take concentration of 2 OH ,but u have taken concentration Of OH only.
The last answer comes 3.4 which is approximately 3 as per options.

1:25:52 tip : the ph is given as 1 so it will be highly acidic then volume of hcl will be much greater than volume of naoh . hence, difference between 2nd option is 10 ml and 4th is 50ml so option 4 will be correct
