Bro I'm still confused!! Poocha ease of absorption hai par sir ne atomic size se question answer kar diya vo bhi galat order main balki poocha to uska ease tha, to order ulta hoga na "Rb>K>Na>Li" 1:07:30
So the ease of adsorption is directly proportional to the charge density and hence inversely proportional to the hydrated size and hence directly proportional to the unhydrated size? Do you agree
Ease of adsorption of the hydrated alkali metal ions on an ion-exchange resin decreases as the size of alkali metal ion increases.Therefore, the ease of adsorption follows the order- Rb
1:08:17 Ease of adsorption of the hydrated alkali metal ions on an ion-exchange resin decreases as the size of alkali metal ion increases. Since the order of the size of alkali metal ion follows the order- Li

For anyone wondering ans at 1:40:10 2H 2 O 2 (l)→2H 2 O(l)+O 2 (g) 5 volume H 2 O 2 means , 1 L of H 2 O 2 will give 5L of O 2 at STP. On the basis of equation it is clear that 22.4 L of O 2 is produced by 68 g of H 2 O 2 . 5L of O 2 is produced by = 22.7 L 68 g×5 L = 224 3400 g H 2 O 2 =15.18 g H 2 O 2 i.e. 15.18 g H 2 O 2 dissolved in 1 L solution will give 5 L oxygen or 15.18 g H 2 O 2 /1000 mL solution. Thus 15.18 g/L or 1.518% solution is known as 5V solution of H 2 O 2 .
In the topic ; Treatment with washing soda, the products of second equation are Na2SO4 + MgCO3 DURATION:- 55:45 - 57:46 Sir galti se Na2SO4 + MgSO4 likh diye.... Thanks me later... ☺️

At 1:07:44, the question is asking about the easy of adsorption of HYDRATED alkali metal ions yes hydrated so in aqueous condition the hydration of Li+ is more so it's size will increase(I hope you all know that in aq. Condition the order of size becomes opp.) And agar size jyada hai toh adsorption jyada hoga kyoki use adsorb karne wala bhi large organic molecules hai R group. So sabse jyada Li+ than Na+ K+ Rb+ answer toh yahi mentioned hai pyqs mai!

I think this is one of the besttttt lecture of hydrogen...he covered all the points and his teaching style is osmmm...(His smile=constant) 😊😊 Let me telll u this is one of the best lecture
16:52 if Hydrogen act as reducing agent it should oxidise....so Hydrogen does reduction so oxidising agent...pls correct if I am wrong or yourself if u r wrong
See H2 is acting as reducing agent it means ki dusro ko reduce karega khud oxidise hoga Waha reaction dekho at 16:42 Pb+2 se Pb bana iska matlab hai Pb got reduced H2 ki wajah se Aur H2 khud 0 se +1 state mein gaya khud oxidise ho gaya

Sir aapke lecture se Sare concepts easily revise ho gaye aur kucch naya bhi sikh liya . Love you sir and whole physics wallah team. Great series for neet 2021 .
40:20 - reactions me aapne a) me Oxidising likh diya it supposed to be reducing agent as waha oxidation hori hai b) me Oxidising hoga as reduction hora hai
See at 41:24 waha Oxidising agent woh hota hai jo saamne wale ko oxidise kare khud reduce ho jaye Jaise waha Na 0 se Na+1 gaya toh oxidise hua Na Aur H2O se H2 bana yaani loss of Oxygen khud reduce hua Toh H2O will be oxidising agent (reactant mein tha isiliye) Reducing agent woh hota hai jo saamne wale ko reduce kare khud oxidise ho jaye Toh F 0 se F -1 gaya reduce hua due to H2O Aur H2O se O2 bana loss of H2 which means H2O oxidise hua khud Hope clear hai

At 1:07:44, the question is asking about the easy of adsorption of HYDRATED alkali metal ions yes hydrated so in aqueous condition the hydration of Li+ is more so it's size will increase(I hope you all know that in aq. Condition the order of size becomes opp.) And agar size jyada hai toh adsorption jyada hoga kyoki use adsorb karne wala bhi large organic molecules hai R group. So sabse jyada Li+ than Na+ K+ Rb+ answer toh yahi mentioned hai pyqs mai!
So the correct option should be d) right ?
🎖️🏅🥇 sir after so many teachers i finally understood hardness of water, these medals are for you
56:19 , Mgso4 ke jagah Mgco3 hona chahiye....
Ryt wahi hoga.... No 1 noticed this actually 🥴
1:08:28 it decreases with increase in size of alkali metal ion. So the answer would be Li+ > Na+ > K+ > Rb+
Sahi toh h
No, adsorption increases with increase in size of alkali metal cation as the surface area increases
No In Aqueous Medium, Size of Cation Order is Li>Na>K>Rb

Sir... Thanks to the whole pw team for their continuous efforts.... Words can't express our gratitude towards u all... Thankx a lot sir... 🙏❤
At 56:25 It should be MgSO4+Na2CO3=Na2SO4+MgCO3
Sir you teach very fast
Your 1:43 hour lecture take 3 hours for me to complete chapter with notes .
Mai thoh 1.5× mai dekh raha hu 😂

Mahajan sir ka yeh lecture .... Mohit sir ke yakeen 2.0 2023 ke lecture se infinity times better h .... Unhone strength tk nhi krayi ... Unka detail lecture sir ke oneshot ke aage kuch bhi nhi ...... 😊😊Amit sir is best for inorganic ...
Sahi bol rhe bhai
Seriously amazing session by Amit Mahajan sir!!!
1.08.17 - potassium is larger than sodium ... so potassium jyada adsorb hona chahiya , right?
See jitna bada cation hoga uska ease of adsorption utna kam hoga
Size ka order Li+ < Na+ < K+< Rb+
Adsorption ka usse ulta ho jayega
Opt d
Itna khushaali brha lecture...😃😃
Pure lecture me mere face pr bhi smile thi....😄😄😊☺️
wahii to kaha se late hh yaar itnii energy

57:40 , Sir in 2nd reaction, will it not be magnesium carbonate?
Yes waha par MgCO3 as a precipitate aa jayega
1:08:11 answer should be option d
Sir 56:33 precipitate should be MgCO3.
Sir the main problem with inorganic chemistry is we forget very often so pls try to make some shortcuts and tricks to remember the reactions and other .......Thank u
th-cam.com/video/1AM7knz-JkM/w-d-xo.html
At 56:19 MgCO3 will be formed otherwise MgSO4 is present in reactant too
6:46 Its from NCERT exercises of states of matter. I have used DRAINEX😆
56:36 in the second reaction it should be written as MgCO3
Yes
I didn't except to complete this chapter with this much clarity
Expect*
At 56:26 it is MgCO3 as ppt on products side
Thanks
I think this is one of the besttttt lecture of hydrogen...he covered all the points and his teaching style is osmmm...(His smile=constant) 😊😊 Let me telll u this is one of the best lecture
💯
16:52 if Hydrogen act as reducing agent it should oxidise....so Hydrogen does reduction so oxidising agent...pls correct if I am wrong or yourself if u r wrong
See H2 is acting as reducing agent it means ki dusro ko reduce karega khud oxidise hoga
Waha reaction dekho at 16:42
Pb+2 se Pb bana iska matlab hai Pb got reduced H2 ki wajah se
Aur H2 khud 0 se +1 state mein gaya khud oxidise ho gaya

Does it cover hole NCERT and Is it Sufficient for neet or not?
According to me
The ease of adsorption is inversely proportional to size so option d should be correct....
At 1:07:45
Poora chapter sir ne khatam kra diya isi lecture me??
Ya part 2 bhi banega??
@@87minutesago1secondago8 it's complete chapter
@Preety are you sure about that?
Then why adsorption of Na+ is more than K+ despite of the fact that potassium size is larger than sodium

You can also convert this video into audio for revision Bocz he is like Sidhi baat no bakwas❤️❤️❤️
At 16:19 it should be Pd instead of Pb...as pb has more reducing character as compared to hydrogen...
Kahin najar n lag jaye sir ki smile ko sab itaa bolte hai hamesha haste raho sir jiiiii😀😀😀😀
57:45 Sir yaha second product MgCO3 hoga
Best revision lecture of Hydrogen on TH-cam.
Your teaching style is just amazing and helping me a lot in my preparation.
I have no words to thanks you, only thing I can do for you is I will always support you and this platform.

@@vishalbhardwaj1016 thanku
40:20 - reactions me aapne
a) me Oxidising likh diya it supposed to be reducing agent as waha oxidation hori hai
b) me Oxidising hoga as reduction hora hai
See at 41:24 waha
Oxidising agent woh hota hai jo saamne wale ko oxidise kare khud reduce ho jaye
Jaise waha Na 0 se Na+1 gaya toh oxidise hua Na
Aur H2O se H2 bana yaani loss of Oxygen khud reduce hua
Toh H2O will be oxidising agent (reactant mein tha isiliye)
Reducing agent woh hota hai jo saamne wale ko reduce kare khud oxidise ho jaye
Toh F 0 se F -1 gaya reduce hua due to H2O
Aur H2O se O2 bana loss of H2 which means H2O oxidise hua khud
Hope clear hai
@@prt4691 bhai tu mereko ye question ka jawab de
H2O2 + O3----> H20 + 2O2
Isme h202 oxidising agent hain ya reducing
@@abhilashh1818 Isme H2O2
O3 ko reduce kar raha hai toh reducing agent hoga
One of the best teacher of inorganic chemistry
Sir aapne ease of absorption wala question galat karwaya
Ease of adsorption of the hydrated alkali metal ions on an ion-exchange resin decreases as the size of alkali metal ion increases.
Since the order of the size of alkali metal ion follows the order-
Li+
