My chem professor is literally no help these days. God bless you. Having no option but to do Chemistry online is difficult! I’m sure a lot of students are having a hard time during this quarantine.

thank you for helping me with online simulation during this COVID-19 outbreak.

This video was beyond helpful, even 5 years later. You're a wonderful educator and explained this complex reaction is such a simple way!

this is very helpful and straightforward, thanks for helping a fellow chemistry student who is barely surviving

The only 15-minute lecture video that I actually watched from beginning to end. This is so helpful. Thanm you so much!

A thank you from Australia!! I’ve got a chem personal project and I’m so glad I found this! Sometimes I’m afraid to ask questions in class so I’m glad I can learn and rewatch your vids until I understand without judgement!

Thank you, I have this experiment in HOL and I had no idea what I was suppose until I saw this video. This cleared things up so well!

this was super helpful for my lab tonight! Thank you for how clearly you showed all the steps!

Thank You!! Now I actually understand what to do in my Chemistry depth study.

There's a spot in heaven waiting for you! You're amazing:)

Literally the best video on titration! Thank you so much

This was really helpful! Thank you so much for the additional information as well!

You have no idea how much you helped me.

I can finally complete my chemistry assignment thanks to you! great video :)

Holy moly thank you so much for this video! We had lab online and in person but still didn’t know how to solve all of this! You helped me and my girl friend so much! Thank you!

Thank you! I appreciate you uploading this!

Thank you, You are my COVID19 online lab hero... I'm your fan #1 !

Have to do this titration alone for a final today and you really helped with my calculations bless you!

I noticed this video was Post for few years now, and it's going to help me today. Thank you

Your explanation is very easy to understand! Thanks!

This is lovely I haven't seen any teaching practical chemistry as you do

God bless you woman. I have seen some senseless videos our school sent us. But this really helped

You are a lifesaver! Thank u so much!

Thank you very much for this video, I now feel confident in my results!

Thank you for your help, lots of love from a Brazilian student who doesn’t have lab classes yet because of covid here :(

You just saved my chem lab grade. Very helpful. Thank you so much!!

Thank you so much. You help me a lot, I appreciate 🌹

Super job. I understand it now because you explained all steps clearly.

Really thank thee for helping me in Chemistry course!

Ma'am you are such a great teacher and this channel deserves millions of subscribers , stay blessed ma'am 💚

Thank you so much this is the best titration video I have seen

bless you. you are really helping me understand what to do for my chem lab.

I'm doing this experiment tomorrow, so thanks for the heads up video

Wish I watched this before my practical! It was on this experiment (chosen by prof. out of all the other experiments). Completely bombed the calculations. This was super helpful and I now understand it 100%. I still have my theory exam which will involve calculations, I hope this will be on it so I can prove what I've learned!!!! Thank you so much for your knowledge.

This is an excellent explanation! Next week I will have chem exam, I think it can help me a lot! Thank u for your video😊

Thank you that was very helpful. I was lost as to how to fill out the lab manual. Do you think you can do a video on stoichiometry? Thanks again.

this is so helpful thank you!

Anne, your video came up when I was searching for titrations! Great work :)

thx for the help 2 but you had a miscalculation for volume of NaOH used for second trial! Still helped

thank you for helping with online simulation of this important chemistry topic during this COVID-19 pandemic and online classes.

Watched your video before my practical exam on titration. Coming back to thanks for the A🥰

this video is very informative and i think this video will help a lot in my upcoming IGCSE Chemistry exam next week thank you so much

Thank you very much. Both content and clarity of your video are excellent

Oh god thank u for helping me w the calculations

I love this .. Such a Great moment WITH U

That was outstanding Thanks for the clear explanations

Thanks ❤️❤️❤️❤️Really for helping

Thank you so much .This helped me so much. I am on 2 week break and I have a chemistry test 2nd day back and this has clarified so much. Just one question, when you put final and initial amounts into the table. Is the initial amount, the amount of titrant that was in the Burnett’s before you added any NaOH? As it says an amount less than 1 but the final amount is around 35? Thanks again

Thank you so much!

Thanks a million!

love how used that jacket is

Thanks a lot, ma'am......this video helped me at the last moment

Thankyou from Australia, we have a prac on this exact titration coming up which goes towards our final score in Year 12 Chemistry, so this really helped :)

thank you

Thank you so much kween!

this video is a god send

Really thank thee for helping me in Chemistry course

Thank you so much for this video. Is there any way you can teach to calculate ph and poh without using the calculator

THANK YOU SO MUCH

Omg! THANK YOU SO MUCH!!! ❤

Hello! Great video is gonna be a great help for my final on this with the exact same chemicals, my question is how would I find avg number of NaOH used in the trials?

hi! this video was super helpful! i just had a quick question. if for my lab, i had used 6.12 g of NaOH, which converted to moles would be 0.153 mol of NaOH, would i use that when calculating the molarity of the acetic vinegar? or would i use the molarity of the NaOH standard solution?

Hello Anne! Thanks for this. I know that the volume of the vinegar is already known but isn't it adding distilled water before reaching the titration may affect the rate at which the vinegar and sodium hydroxide reach the end point? Or that could be ignored and assume that it doesn't affect the titration process.

Many many thanks

Thanks a lot

Awesome! Anne

What a video mam,, Wow ⚗️⚗️ Keep making video Your big fan from India ,Mam

Thanks very much.....

Hello Anne, Thanks a ton for the video. I need one more help if you can. Can you please explain how do we convert molarity to mass percentage?

Hello How can I get the summary of the experiment?! Please help me I have to write a summary about that😫and I have to work on a project for design.

Do I need to add water to the flask if i am measuring the concentration of acetic acid. will not adding water produce diffrent/wrong result?

Can you tell me what factor affects the rate of this reaction and how?

I have a question with the 2 decimal places when marking down the volume of the titrant(NAOH). Wouldn't it be one decimal place as you can not be more accurate than the measurement equipment(the burette) itself? Or maybe is your burette just more accurate than the one I have at school as the one I use during practicals only measure to 0.1 of a mL. This was a very informative video and has cleared up many things for me. Thanks!

thanks

Thank you thank you thank you

Thank you very much for this video.. 😄

Hi did u make an aliquot of the vinegar? Since once I tried it in school the phenolphthalein indicator did not show at all. Thank you

Hi Anne, are you able to tell me how you know you have reached equivalent point? If I understand this correctly, the end point is when the solution becomes pink after swirling the flask, but im struggling to understand the difference between these two points? Thank you!

What is the inital and final reading of the buret? I can not zoom in on the video

This video is very helpful. Can I know what brand of vinegar you used?

Would you be able to share the mass of the empty vial and the mass of the vinegar so I'm able to find density? Thanks!

What was the initial and final reading of the acid? I know the volume of vinegar was 20.00 mL.

Thank you soo much mam, can u please put the reference for this method??

Does the added water to add the suspended drop not effect the endpoint?

Can i ask where did you get the 0.50m of NaOH? Is it in given or you just right it? Please help me

hi professor!!! may I ask for any references you used for the accepted value (13:30) for concentration of acetic acid in vinegar?? this will help me a lot for my laboratory work, thanks in advanced!

How the calculated molarity of vinegar could be affected if I forgot to rinse the burette with the titrant solution in the beginning?

Hi . I have a question. Was that a 5% vinegar from supermarket? Thank you

Is bioenzyme acidic or alkaline in nature?

Hi Anne, just a quick question why did you do all the calculations separate and then average the Molarity. Would it not have been quicker if I just averaged the titre values and completed the calculation once?. I appreciate hearing from you soon , thanks for this video!

May I know where did you get the accepted value?

Hello, can I ask what was the equivalence point on the experiment? How can we identified it

Can I change the initial volume of vinegar to 15cm^3 instead of 25cm^3 and use the 0.1M?

how do you know how much vinegar to put inside the Erlenmeyer flask?

How do you get .50 for the NaOH standardized mole?

Hi ms, I have heard that you have to dilute the vinegar first before the titration. Is this necessary?

This video helped me thank you so much. And I want ask you that when calculate the average volume of NaOH should we get the .01 values? If yes, should we get the lowest numbers or numbers with .01 decimals?

Was the phenolphthalein add to the burette or in the flask?

can i ask how many drops of indicator were used for each trial?
