✅ In this video,

✔️ Class: 12th
✔️ Subject: Chemistry
✔️ Chapter: Solutions (Chapter 1)
✔️ Topic Name: NCERT Solutions
✔️ Topics Covered In This Video (By Hemant Sir): Explore the world of Chemistry with our 12th-grade class! In this video, we'll be delving into NCERT Solutions of Chapter 1, "Solutions," and covering important problems in detail.
=======================================================
00:00:00 Introduction : Solutions - NCERT Solutions
00:00:59 Exercise : Que.1 TO Que.10
Que. 1 Define the term solution. How many types of solutions are formed? Write briefly about each type with an example
01:25:04 Exercise : Que.11 TO Que.20
Que. 11 Why do gases always tend to be less soluble in liquids as the temperature is raised?
02:42:24 Exercise : Que.21 TO Que.30
Que. 21 Two elements A and B form compounds having formula AB2 and AB4. When dissolved in 20 g of benzene (C6H6), 1 g of AB2 lowers the freezing point by 2.3K whereas 1.0 g of AB4 lowers it by 1.3 K. The molar depression constant for benzene is 5.1 K kg mol-1. Calculate atomic masses of A and B.
03:35:12 Exercise : Que.31 TO Que.40
Que. 31 The depression in freezing point of water observed for the same amount of acetic acid, trichloroacetic acid and trifluoroacetic acid increases in the order given above. Explain briefly.

The most amazing teacher I have ever seen Indeed is Him! 🥺🥺🎊💫

[anamaysinha]

1:38:05 instead of 10^-3 it should be 10^-4

[AnasSaqlaini-obzc]

Answer 5= Glucose=0.099
= Water= 0.901
Answer 28= 1.42
Answer 30= molar mass = 122
= 4.575
Answer 33= 0.28125
Answer 37= 0.599

3:52:40 sir 19g

3:57:17 sir approximately 2.8125 × 10^(-3)

[Siddhi-jg]

3:33:58 it should be 122 instead of 132

[LoveKumsin-pmrj]

Sir You are a very good teacher because you teach very well, I understand what you teach very well in one go.

[ArpitaYadav-hh]

Question no. 30 me molar mass 122 hai
Answer hai 4.575 g

[friction]

Sir D and F block elements class 12 inorganic kra do

[Kittyk]

2024 25 batch wale attendance lagao ❤🎉

[CheraTana]

Sir I have questions if you ware so good in studies and know everything and also get good graades, why you didn't become a teacher why not a doctor or engineering

[Abhishekshukla-pcsz]

sir aaapne molarity aur molality ka formulaa interchangee kr diyaaa

[Janvi_Bhalla]

Thank you so much sir for this amazing session, so helpful and understandable. ❤️❤️🙏🏻🙏🏻

[KaranGupta-hitc]

Q 28 answer 1.42. Q 30 answer 4.95

[sudeshdevi]

Thank you so much sir for this amazing lecture 🙏🏻 🙌 👏 ❤️ 😊 this will help me a lot 😊❤

[AnanyaSutradhar-sk]

molality = moles of solute/mass of solvent[kg/g] it will be but sir u hv written vol of solvent in [kg/g]

[AyushSingh-jmjv]

There were many silly mistakes in the calculation but overall explanation was good.

[Hydrogen-Atom]

3:54:15 how can u put those value in the ratio bcz one is in centigrade and other one is in Kelvin?

[SunitaBauddha-dgmi]

Sir thanks for this session it was really helpful 😊😊
