7:02 Colligative Properties :- 1. Relative lowering of Vapour Pressure 2. Elevation in Boiling Point 3. Depression in Freezing Point 4. Osmosis & Osmotic Pressure
Sir apki 10 days pledge superhit hogi sir thumbnail per apni photo change kar lo 😊😊 aab to aap India ki most power full series leke aa rahe h ❤️❤️10 Pledge ❤️❤️❤️
There are 4 types of Colligative property. 1. Osmotic pressure 2. Elevation in boiling point 3. Depression in freezing point 4. Relative lowering in vapour pressure
At 41:32 sir yaha pe chloroform and acetone do form a solution with negative deviation but last me from Raoult's law likha h jo apne bola sahi h but kaise..??? Negative deviations were non ideal solution and they don't obey Raoult's law... Please explain sir And here one more there is a question jaha me molality k bare me tha waha aapne glti se shi kr diya tha per lit. Wale assertion me please correct these things BTW Thanks sir for helping us✨☺️☺️
Type of colligative property!! Elevation of boiling point Depression in freezing point Osmotic pressure Relatives lowering of vp 36:04 molality is define as in the terms of kg not in litre
Thank you sir bcz of you mrra ye chapter me mcq me confidence agya or mera sara answer shi tha 1 AR glt tha bs.... You are on fire sir 🔥... Ek request sir plz numerical ka session bhi lelo plz plz
Sir you are the best.. you have made everything so easy for us to learn so systematic so neat... we just have to study all the other efforts have been taken by you sir... thank you so much sir... you are god's gift to us... Keeping going sir always full support... Hope your prayers and blessings are always there.. LOVE YOU SIR
Sir mae state board se hu...or hum sab ko sabse jada objective questions ki tension hoti hai...marks un me hi kat jate hai.... please bataiye...kya ye sufficient hai ???

Sir in question 20 many websites including byjus and other have given option 3 correct but arihant exampler has given option b correct, but u have done option a correct. Pls reply as soon as possible
7:05 , colligative properties are following 1. Relative lowering of V.P 2. Elevation in B.P 3. Depression in F.P 4. Osmotic Pressure
20:36 20> Sir option (iii) will be right answer as its a ratio of moles after diss/association to initial moles So...
Yes bro
Yeps !!
Correct
The value of i is differ brother you just look at the table 2.4 on 59 page no.
32:02
Sir correct option will be I
Hcho
3 write hai
Molality: It is defined as the number of moles of solute dissolved per KG of solvent
Sir in question 20 at 20:45 the correct answer is C option because van`t hoff factor of NaCl is 2.🤔
7:02
Colligative Properties :-
1. Relative lowering of Vapour Pressure
2. Elevation in Boiling Point
3. Depression in Freezing Point
4. Osmosis & Osmotic Pressure
Sir apki 10 days pledge superhit hogi sir thumbnail per apni photo change kar lo 😊😊 aab to aap India ki most power full series leke aa rahe h ❤️❤️10 Pledge ❤️❤️❤️
A
D
What's wrong with the thumbnail?
👍
19:43 option a and b both are correct 1st for osmosis and 2nd for RO . Ist case me agar Kam pressure lagega osmotic pressure se to osmosis hoga hi na
There are 4 types of Colligative property.
1. Osmotic pressure
2. Elevation in boiling point
3. Depression in freezing point
4. Relative lowering in vapour pressure
sir at 20:45, shouldn't the answer be (iii) as NaCl is a strong electrolyte the van hoff factor should be constant = 2 (Na+ and Cl-).
Thanks 🙏
Yes becuse i doesn't depend on concentration,the values of i of Nacl will stay the same on all the concentrations given above
Types of colligative property
Elevation in Boiling point
Depression in freezing point
Relative lowering of vapour pressure
Osmotic pressure
7:06 RLVP, Depression in freezing point, elevation in boiling point, Osmosis
36:08 Molality is defined as ratio of number of moles of solute to weight of solvent(in Kg).

At 41:32 sir yaha pe chloroform and acetone do form a solution with negative deviation but last me from Raoult's law likha h jo apne bola sahi h but kaise..??? Negative deviations were non ideal solution and they don't obey Raoult's law...
Please explain sir
And here one more there is a question jaha me molality k bare me tha waha aapne glti se shi kr diya tha per lit. Wale assertion me please correct these things
BTW Thanks sir for helping us✨☺️☺️
Colligative property are as follows: (i) RLVP (ii) Elevation in B.P ( iii) Depression in F.P ( iv) Osmotic Pressure
Type of colligative property!!
Elevation of boiling point
Depression in freezing point
Osmotic pressure
Relatives lowering of vp
36:04 molality is define as in the terms of kg not in litre
You are so cute
Can we friends 🤭
Chi Chi
Completed one shot of solutions.
Doing mcqs first ,after one shot
Then will do the PYQs and then the special videos.
Colligative properties
1.relative lowering of vapour pressure
2.Elevation in boiling point
3.depression in freezing point
4.ossmotic pressure
All depends on no. Of solute
Thank you sir bcz of you mrra ye chapter me mcq me confidence agya or mera sara answer shi tha 1 AR glt tha bs.... You are on fire sir 🔥... Ek request sir plz numerical ka session bhi lelo plz plz
Okk
36:03 no. Of moles of solute/1kg of solvent.
32:12 option 1 is correct
36:04 molality - no of moles of solute in 1kg of solvent

Please maths ke liye tips do is ncert enough
Sir please tell us about power notes
Is it alternative of short notes?
usme numericals bhe rhnge .
Sir ...your notes +your pyqs series+ your mcqs series....is enough to score 95+ in boards
Yaar pdf kase milegi bata do bhai koi
Ncert???
Sir yeh dekhne ae concept bhi puri trh clear ho jynge ?
How many students accept this pledge
40:38 sir isme b aayega ... interrelated nhi hai...
27:30 m1v1 + m2v2 = m3(v1+v2)
Watching it second time for completion in proper way ❤️.
Pyqs krne hei iske baad solutions k bass...
Edit : completed
Sir mae state board se hu...or hum sab ko sabse jada objective questions ki tension hoti hai...marks un me hi kat jate hai.... please bataiye...kya ye sufficient hai ???

Aap konse batch ke hoo
Thanks a lot sir ❤️
Sir in this pledge will there be only mcqs ?
im also confused bro one shot to daala hi nahi sir ne
20:39 answer (c) is right
Yess
@@Animewithgoddess how
Almost All concepts are used superb sir❤
Thankyou sir for your hardwork for every student
In ques 24 - M1V1 =M2V2 vala relation to molarity k lie hota h na molality k lie thodi na
40:43 mei A&R ka koi relation thodi h?
Right brother
Sir in question 20 many websites including byjus and other have given option 3 correct but arihant exampler has given option b correct, but u have done option a correct.

present sir.....!!!!
Thanks sir for amazing session 💙💙💙
Sir is this usefull for 2024 board exams...
CONFIDENCE LEVEL AFTER THIS🔥. AAP LOG BHI AA GYE 27 KEE LIYEE? 😂
At 05:12 sir ncert me likha h it depends upon the nature of solute and solvent as well as temperature and pressure.....
28:34 the question is to find molality not molarity
sir aapka one shot dekhke questions ko bahut ache relate kar pa rahi hu bahut mazaa aaya sir thank you sir🙏🙏
Thank youu soo much sirr.....for your hardwork for us🤗
Thanku sir 😇
Thank you sir itna acha session lane ke liye
