I think in q2 part b since the conc of HCl and NaOH are equal, the sum of their pH values must be equal to 14. Let x = pH of HCl and y = pH of NaOH, we can form 2 simul equations: x + y = 14 y - x = 11 => x = 1.5, y = 12.5
Sir for 21:28 i did ((PH of acid = x)), ((PH of base = x + 11)) so PH + POH = 14 x + ( x +11 ) = 14 2x +11 = 14 2x = 3 x = 1.5 so PH of acid = 1.5 and pH of base = 1.5+11 10^-PH = [h] [h] = 0.0316 M
my paper is just after 3 hours, need luck bro, literally paper is today!!!!!!! Hoping for the best!!!! and best of luck to any of the candidates looking at this comment@#
for q2bi concentration of NaOH and HCl is equal so average pH is 7. we know their difference is 11 so it would be 1.5 and 12.5 because average of these two is 7
HELLO SIR, My As exams are over today...and I WANNA GIVE U A BIG THANKS FOR EVERYTHING SIR...Ur vids always helped me man...i wish i knew u could find u...ur literally batman bro....i wanna give u 55000 HUGS BRO...THANK U
Sir will our overall A level grades be calculated by adding raw marks of AS and A2 from the threshold or by just adding the percentage uniform mark? Please answer i really need this clarification
i guess they wrote 1.5 ph for acid as its a strong acid with min low ph and 12.5 ph for NaOH that is maximum ph we can get for an alkali also they ensured and took those values whoes difference is 11
Search for practical guide videos, take notes and then watch all the practicals from UA-cam mentioned in practical assessment area in the syllabus. Do past papers mole equations watch from UA-cam if needed ( you don't need to do the experiment just take experiment results from ms and then do the maths)
Hi sir, can you please solve the chemistry AS FM 2024 paper 1 and 2 it'll be a great help for students who are sitting for AS upcoming mj session. I have the papers Is there any way I can mail you? Specially paper 1
57:25, your solving stands out from the rest because you solve with proper explanation and giving tips and tricks along the way.

why would be the sum of PH of two different solutions be 14?
@@HasanAli-ef4hg because ph+pOH=14
@@joyetamoietree2122 of the same solution equal 14, not different ones
@@HasanAli-ef4hg cuz they have the same conc
nice thinking there bro
pretty cool hearing your lore, hope you make it to the UK, best of luck!!
I have my paper tmr im ded but thank you so much these vids really helped
Sir for 21:28 i did ((PH of acid = x)), ((PH of base = x + 11))
so PH + POH = 14
x + ( x +11 ) = 14
2x +11 = 14
2x = 3
x = 1.5
so PH of acid = 1.5 and pH of base = 1.5+11
10^-PH = [h] [h] = 0.0316 M
Damnn, makes sense
Yeah bro I’m failing
Yoo chill man
Don't say that. I'll help you out. Contact me. My Instagram is @husnain_clips

You got this!

It’s was quite a difficult one it’s may June 2024 paper 41. Once you get it do it and check 😢😢
for q2bi concentration of NaOH and HCl is equal so average pH is 7. we know their difference is 11 so it would be 1.5 and 12.5 because average of these two is 7
Edging to this and my exam is tmr. Thanks for all the help
Best of luck!

hey bro can you please do febmarch2024 A level?
Love from Bangladesh 2din por Amar Chemp4 mara jacchi
Q2 is the worst🤧
I was only able to get 1 mark for the definition 🤐
Sir will our overall A level grades be calculated by adding raw marks of AS and A2 from the threshold or by just adding the percentage uniform mark? Please answer i really need this clarification
Threshold
I think q2-*p(OH) is equal to 14-pH ……therefore (14-pH)-pH=11 solving this we get pH as 1,5 then we just do 10^-1,5 to get 0,0316
YES WE NEED SPECTROSCOPY TUTORIAL
For qs 2c part (iii), how come h2SO4 undergo dissociation twice?? And how do we know that dissociation has occur. 😅 32:53
sir pls make more videos of solving as level chemistry p2 papers
i guess they wrote 1.5 ph for acid as its a strong acid with min low ph and 12.5 ph for NaOH that is maximum ph we can get for an alkali also they ensured and took those values whoes difference is 11
Guys October 23 was flames 😢😢😢had to rewrite
yeah.... we'd like the spectroscopy tutorial
U sais that for acid hydrolysis of amides, u get cooh and salt...isn't it cooh and amine? 😢
