📒Notes :
1) 7:52 ◾Y(b) = P(b)/P(t) = Xb(Pb0)/ Xa(Pa0) + Xb(Pb0)
2) 14:24 ◾ΔTf = i(Kf)m ◾Change in temp is equal in kelvin and Celsius ◾water d=1g/mL➡500mL = 500g ◾If density data is not given in question then assume molarity = molality ◾K = c(α^2)/1-α
3) 23:21 ◾ΔTf = i(Kf)m
4) 27:29 ◾ΔTf = i(Kf)m and Tf = Tf0 - ΔTf
5) 30:06 ◾P0-P/P0 = X(solute) ◾Lowering in VP = P0-P, ◾PV=nRT, mole concept ◾Na2SO3 when dissolved in water ➡5millimoles to 15millimoles
6) 38:49 ◾AB2➡n = 3 ◾ΔTb = i(Kb)m and Tb = Tb0 + ΔTb
7) 41:13 ◾Pt = Xa(Pa0) + Xb(Pb0)
8) 43:26 ◾P(gas) = K(h) X(gas), ◾molar solubility = molarity
9) 50:16 ◾boiling point of both are equal : i1m1 = i2m2, ◾1g = 6.023×(10^23) amu
10) 57:16 ◾ΔTf = i(Kf)m
11) 1:00:02 ◾P(gas) = K(h) X(gas), using approximation X(gas) = n(gas) / n(h20)
12) 1:03:14 ◾π = iCRT
13) 1:05:49 ◾i more = freezing point lowest = depression more
14) 1:08:16 ◾fractional distillation = difference in boiling point of two liquids 20° or more. ◾H-bond = more BP
15) 1:11:10 ◾dimerize i = 1+ [(1/n)-1]α, ◾If α not given assume α = 1

Thank you ❤ ....

Video Starts 7:23 but try not to miss the starting advice sir has given, That seems really helpful....

Sir there is calcution mistake in 1st que ans is one You have written 90*0.6=5.4 instead of 54

at 13:14, 90*0.6 is 54 not 5.4, so the final answer comes out as x = 1

He is now my physical chemistry teacher at allen kota...
Just brilliant teacher ❤

54:45 there is a degree of dissociation of 0.4. So put it by which i=2.6

50:09 answer is 25 not 1389 simple according to Henry law solubility is equal to partial pressure by Henry constant

38:00mins I also did same mistake!!! Abse kbhi nhi krenge aisa always check whether dissociate or not

Sir, at 57:13 you put the value of degree of dissociation as 1 but in question it is 0.4
