7:00sir but I think should be that phenolphthalein changes colour when the environment is weakly acidic of ph 8 to 10 range. Is there any good soul who can help me out with this?
@@harshsingh22105 sodium carbonate se jo sodium bicarbonate bna hai wo dono same equivalent se bne hai dono ka equivalent same hoga,,, tbhi answer 55.8 ayga ......ONCE DO CALCULATION ...........😇
Btw, phenolpthalein pink hona chahiye na NaOH ke saath? Kyoki uska color change karne ka range around 10 pH tak hain, usse zyada hone se to ekdum se colour change hona chahiye...
Haan, maine experiment kiya tha. Reaction ke acidic hone par reaction backwards chale jaata hain jisme H+ ions wapas Phenolpthalein ke saath react karte hain

I had so much confusion in this topic... After watching this one video its crystal clear thank you sir
Sir electrochemistry wala conductometric titration please!
Please make it to reach sir
Sir please make videos on solubility of organic compound in NaOH, How to find Acidic Hydrogen
Sugar in coffee
Faisal sir oppppppppppppp🥰🥰🥰😍😍
It was too good , really helped me to understand the whole concept easily
IIT you have to be ready we are coming.
Same here.
thik hai
Definitely💪
welcome to our club
May we be prepared coz advanced is coming 😅
Thank you very much sir, I was very confused about the usage of indicators and when they change their colour❤
Pehle 3 minute to kuch bhi samjh nahi aaya tha .😢
Solid Explanation...
Mind blowing explanation ❤..Thank u sir
the best video sir you are a legend of chemistry love you a lot sir you made this so damn clear!!!!!!!!!!!!!
Sir pls make video on soft- hard nucleophile
Sir please continue this series
Thank you sir
Very good teaching sir

Bestest Explanation
2nd question main Molar mass me mistake hai kya ?
Sir sequential reaction main rate kese niklte h ispe bhi video bana do please
thank you so much sir excellent explaination
Sir NaHCO3 to pel kar NaOH se rxn kar lega aur NaOH bachne par wah tab HCl se react karega kyoki initially Concentration of HCL in solution = 0

Almost aisa type of question 2022 advance mein tha...
Thanks sir mera ye topic mei kafi confusing tha ab Clear ho gya
Thank you very much sir 😊
Thank you very much, sir.
Sir please your videos on all topic.becz many more students depends only on you for their study😔🙏
Sir methyl orange wale question aap 2 se multiply krna bhul gye hain ....2×milliequvalent of Na2Co3
Kyu bhai 2 kaha hoga jo kiya shi kiyea na2co3->nahco3 mai change ho rha toh (equi=1) 1hi aayega

Sir please make more videos on physical chem pls
Sir please make more videos like this in physical education i really need it 😊😊❤❤❤❤
Physical education 😂😂😂

Sir phenolphthalein wapis colourless ho sakta Hai acidic ke contact mein aane par?
Haan, maine experiment kiya tha. Reaction ke acidic hone par reaction backwards chale jaata hain jisme H+ ions wapas Phenolpthalein ke saath react karte hain
Thank you sir .excellent 👍
Superb sir
Where will we find its pdf?
Thanku sir ❤❤❤❤❤❤

Great sir u r awesome
Sir please make video on second law of thermodynamics and real gas equation
Please sir it is request
Sir bht acha pdhate h
Sir you are god
Baap teacher op ❤
11:27 If solution is highly basic,then its weakly acidic right?
So why wont it change colour?
#PWDOUBT
U can see this through value of ph
In highly basic medium value of ph will be above 12
And in case if weak acid... It will around 6

Sir bikul news reporter ki tarah bolte hai
10:02 kisko padha rahe ho sir 😁
ye baat to manna parega ki jitne bhi musalmaan hai wo conversion me expert hote hai

Tumhari Amma ka double titration kar diye kya kisi Muslim ne 😂😁😁 jo har ek vdo me conversion conversion chilla rahe ho 😁🫢🤭😁😁😁
Hasn bhai sahi bola, avoid them as you can, always ready for brain washing
Unhone kiya kya lekin?
