We would just like to say again Thank You for your kind comments and suggestions. We are always trying to improve and although this year has been hectic, we are going to try and get some more videos up pretty soon! Watch this space! Any suggestions or comments would be greatly appreciated!
Thank you. Can you do or explain if you use a known sample solution of say "wine/grape juice" and how to calculate properly the TA levels doing titration. I'm assuming the concentration of NaOH here was 0.1?
Many thanks for the different comments and suggestions! We will try to get back to as many as we can. We are looking at doing different videos, so if you have any suggestions please leave a comment! Thank you for watching and hopefully it was of some use!

i think the burette should be filled with hydrochloric acid and not sodium hydroxide because i had recently done a titration of standardization of sodium hydroxide using hydrocholric acid
It does not matter which you put into the burette. Either hydrochloric acid or sodium hydroxide is acceptable, all that changes is the end point. If it is hydrochloric acid in the conical flask, the end point will be a pink colour. If sodium hydroxide is in the conical the end point will be clear. Either way you will still be able to calculate the concentration of either solution. Sodium hydroxide can block the burette so this is why we have done it this way :)
No if you use universal indicator it will only tell you the ph and it would be difficult to determine an end point. Phenolphthalein is used as it gives you a clear end point
victor harris No Sir the type of indicator depends upon the of base. For strong bases like NaOH and KOH you have to use Phenolphtalein and for weak bases like Na2CO3 or NaHCO3 you should use Methyl Orange.
Good presentation, however I have one question. After ionized the burette with distilled water, don't we need to also rinse the burette with the solution(NaOH) before titration it with the titre?
I wonder whether or not HCl and NaOH in the video can go into the sink directly as those chemicals shall have to be put into a waste container. Also, it might not be safe to use such types of gloves for this experiment. Normally, in the lab, we have to use MAPA ultranitrile gloves (the green ones) for handling strong acid and base.
The HCl and NaOH was at a concentration of 0.1m for both and is safe to into a sink as they can be rinsed using normal water. Always check your own risk assessment and local environmental policy before disposing of chemicals. The gloves in this case are Vinyl and can be used for this practical as long as the person using them is not allergic to vinyl. Nitrile gloves is always preferred
In the lab safety lecture, I always teach my students to wear least amount of jewelry coming to a chemistry lab, best not wear any jewelry at all. Now, one of my students just showed me this video, where the model doing titration here is wearing three rings and multiple bracelets. What a slap in the face, and a dis-service to the vast chemistry instructors like me.
Sorry I'm confused, why was phenolphthalein used? Isn't the equivalence point of Phenolphthalein way above 7 and so when the slightly pink colour is reached, the solution would be basic? And since this is a strong acid and strong base being titrated with each other, shouldn't the end point of the indicator match the equivalence point of a pH of around 7, not above 7? Other than that which confused me, this was a very clear and helpful video.
I have also wondered about this, however, almost all resources I've found describing titrations with HCl and NaOH, they have used phenolphthalein... So I am guessing that this is just standard!
You're technically correct although this is why you are only after a very faint pink colour change and not a deep pink colour change as that would indicate it was way above the Ph of 7. Whereas a slight pink colour change indicates its very close to a pH of around 7 (neutral).
Jennifer Mitchell It depends upon the nature of base. For strong bases like NaOH and K0H you have to use Phenolphtalein and for weak bases like Na2CO3 and NaHCO3 you should use Methyl Orange.
Yes, the burette has been condition with sodium hydroxide as it will have an effect on the result. If it is not condition properly and it has not been cleaned properly it may stop the titration from working.

Tomorrow I have a practical exam, and this demonstration is really helpful. Keep up the good work.
+Tania Tiara Thank you! Although late, we hope the practical exam went really well!
Tania Tiara same here
Mine also
Hope,you,didn't drink any acid during pippeting
Nice
Thanks sir needed it for our lab exam.Love from India
Monday I have practical in physical as it is...I'm so thankful for this video & for u...
THANKU SO MUCH SIR

This helped a lot, I have a practical exam tomorrow and this was a wonderful revision. Thanks
My god such a good explanation!!
Thank you for your assistance sir!😁😁
Thank you. Titration well demonstrated.
my Q. does the conical flask need to be rinsed with titration solution ?
Aren’t you supposed to keep swirling the flask as you add the HCl ?
This helped me soooo much thanks 👌
tnx for the video, it was helpful to me.Keep up the good work.
Will the observation be same if I use sulphuric acid instead of hcl?
Thank you very much for such a clear and understandable lesson🎉🎉 brilliant.

does the conical flask need to be rinsed with titration solution ? please could you answer me
Does anyone know the volume for the NaOH? Or the Molarity?
Dude i love this it helped out alot
I have the first practical of my life tomorrow since I'm in class 11th😅
Thnx a lot for this video!
It really was a great help 😊

is there any video related to NaOH as the unknown and HCl in the burette
Tomorrow l have practicel exam and you helpful me...thanks very much👩🔬
حتى انا الله يعين ...كيف كان اختبارك؟
Thanks for the video... tomorrow i'm having my final lab test on titration and this video is really helpful .. its the best! Thank you so much sir
No problem! I hope your final lab test went well
it did!!!... but i was so panicked that i broke a pipette. i got so scared so hid it in the cupboard
Don't be worried about breaking equipment, accidents happen and the cost of a pipette will be tiny. We are glad it went well
Why do we need to neutralise two equal volumes of sodium hydroxide - one with indicator and one without?
Well done , very helpful thank you👍🖒
Tomorrow I am having practical exams and it has proven very helpful thanks

hello. do you have a video on the calculations??
Thnx sir, you helped a lot
Und wie viel hast du jeweils verwendet? Wie viel Säure und wie viel Lauge?
Thks for thé démonstration
Thanks alot for the video it really does help alot
nasib abdul We are glad you found this video useful! Thanks for viewing.
Thanks a lot sir and this is very Unique. Take care
Thanks sir you helped a lot
Thanks for the video.
We can repeat the experiment by using HCl as standard solutions not NaoH???
Thankyou so much for the video. helped a lot! :)
No Problem, glad we could help
Thanks so much for this
Can methyl orange be used as the indicator sir?
Our teacher said the pipette is marked at 20ml and we did all calculations (like taking the vol of NaOH as 20) based on that
assisted so much. nice video thank you
No Problem, glad it was an assistance to you
Thanks for this video
thanks this really helped
خیلی عالی است
What if parallax error occurs at the time of reading final volume....... what's the solution for it???
How to do it without pipette filler?
i think the burette should be filled with hydrochloric acid and not sodium hydroxide because i had recently done a titration of standardization of sodium hydroxide using hydrocholric acid
we done it the same way
Mohamed Amiin NaOH is a strong base so you have to fill it in the burette.
It does not matter which you put into the burette. Either hydrochloric acid or sodium hydroxide is acceptable, all that changes is the end point. If it is hydrochloric acid in the conical flask, the end point will be a pink colour. If sodium hydroxide is in the conical the end point will be clear. Either way you will still be able to calculate the concentration of either solution.
Sodium hydroxide can block the burette so this is why we have done it this way :)
If we fill Naoh on burette it will get deposited at the end and might get error

شكراً🥰
Can you simply use Universal Indicator for this?
No if you use universal indicator it will only tell you the ph and it would be difficult to determine an end point. Phenolphthalein is used as it gives you a clear end point
Long live your hand, doctor
Hey could u use methylorange indicator as well

You are quite correct! Always condition all pieces of equipment before using
What is the analyte
Sir please tell me how we calculate amount of copper present in sulfuric acid solution
Thank you so much
Not a problem!
What is that pippet filler equipment called? Thats awesome, usually i still used bulb
It's just called a pipette filler
Tq sir

no subtitles of the apparatus names
thank you so much.. so helpful but I have a question why we just need to rinse the conical flask with water only ?
No Problem! Just to make sure that it is cleaned properly. You will have to condition it with whatever your putting into the conical
Thanks alot this is helpful but if I suck wit my mouth instead of pipete filler
Thanks
Awesome

It is an indicator..
Mohammad Naqvi why should use the only penopthlin while titretion...??
thanks for the video! HCl down the drain??
thank you for watching, because it is dilute all it will do is clean the drain. H&S followed
Tomorrow we have a little quiz in this experiment, i had fun and learned new things watching and doing this experiment.
This is really very useful
Superrrrr

shouldn't the burette have been conditioned by running NaOH through it??? or does it not matter
Yes, the burette has been condition with sodium hydroxide as it will have an effect on the result. If it is not condition properly and it has not been cleaned properly it may stop the titration from working.
