Tomorrow is my practical and it is helping me alot From Pakistan

Thanks a lot such types of video uploaded. I see and saw your all video and i feel very happiness. Great wishes for you and your channel.

Thank you for complete step and most easiest method you are using. I never regret of knowing this great Institute of Learning. Nevertheless, free fatty Acids determination was not done in this video

Thank you for your upload videos and I'm very interested to learn that teaching for easily understanding!!!!❤❤❤❤ I'm new for your channel and I will introduce my position to you!!! I'm one among chemistry student: 1. Under graduate, 2. Bachelor degree, 3. 4th year Thank you so much and I will follow you always !!!!!

MicroChem's Experiments people, I just saw your posts today and you are such smart, human angels for sharing your knowledge in such a simple and easy way to understand. Thank you so much! May God/Karma/Life blesses you and your loved ones today and always! Do you have any videos of how to prepare samples, standards, control, and blanks for ICP-OES? And how to do analysis with a GC and an UV? Thank you, you are appreciated!

Miss thanks for sharing, yours methods are so easy which helps easy understanding. Keep it up.

Oleic base oil me factor 40 nahi 28.2 hota hai ffa ke liye Acid value 2 multiple of ffa factor matlab 56.1 hoga Calculation ffa= b. Reading *28.2*normality of naoh --------------------------- Weight of taken sample

Something is not right I think formula molarity mentioned 40 but actual sodium hydroxide 28.2 is right

my keen request to post a video on lipase estimation by titration method for flour samples .....

Thanku so much Mam Acid value of oil experiment ke liye🙏🙏🙏🙏🙏

Can I use this method to know bacterial acid value? And my lipid content of bacteria is. 0085gm then the procedure will be the same? Like 50 ml ethanol etc

Thanks so much Maam For giv6 In detail knowledge for us

Is it okay if im using methanol instead of ethanol?

This is great! Thank you :D

NOTE: There is a mistake in the formulae of acid value, mentioned in this video, and the formulae for FFA is not given in this video. Both corrected formulae & calculations of Acid value and FFA are given below: *Acid value (as oleic acid) = 56.1×V×N --------------- W So, Acid Value (mg/g) = 1.6 *Free fatty acids (as oleic acid)= 28.2×V×N --------------- W So, FFA = 0.805 percent by weight

Thanks a lot for your effort. What is the range of acid value?

hello ..i have a doubt ....to get FFA in percentage wew have to use the same formula and also FFA does not have any unit....another question can i use formula for the estimation of FFA in Pearl millet flour..? kindly give me a suggestion...

UTU Chemistry lab teacher........🚀🚀

Thanks for those videos❤️‍🔥❤️‍🔥

very informative video...

Hello sir/mam, First of thank you so much your videos is valuable for foods company’s. I have two help from your side so 1st questions > how to determination of oil% & protein in Groundnut oil cake ? 2nd questions > how to determination of oil % in Groundnut seed (Peanut) ? Please sir/mam i hope you are making this two questions videos share on youtube…

What is the difference between ffa value and acid value? And also mass of oleic acid is 282.5 so why 28.2?

Excellent video

Hello, I have some questions. What is the difference between normality and molarity? What is the purpose of standardizing the solution? Finally, why do we need to do the first titration of the ethanol?

But the oil samples doesn’t mix after boiled

How to avoid measuring mineral acids (e.g. sulfuric acid) and organic acids, only I would like analyze Free fatty acid content.??

When I needed to get Acid value in our laboratory for fats I used 0.1 N NaOH for titration , but when I calculated I multiple by 56.1 . our specification in our laboratory said that. Is that right?

Hi, thanks for the video. Why do we boil the ethanol-sample solution and what percent phenolphthalein solution are you using? Also, can I neutralize ethanol using KOH instead of NaOH? Thanks again!

great work

How to find out free fatty acid value in cake mix?

i wanna ask, we do the titration while the mixture is still hot or not?

Thanks for sharing easy way to learn. Why you boiled the sample

from your test how can i measure the amount of insoluble matter in alcohol amd water

What is the unit lf the final value gotten. Is it in percentage or mgKOH/g

= 28.2* T.V * Normality NaOH/Weight of sample

Great video still have question when I want to measure the acid value of candelilla wax it starts to solidified in the middle of titration ? How to solve this ? And will it affect 9n acid value?

Thanks from your good video. I have a question. Can we use acetic acid 33٪ instead of concentrated by adding three times more acetic acid ؟

Thank you so much

Very good bhai

Only 2-3 drops of phenopthalein indicator is added what if we add 6-7drops.

Please check my procedure to help me whether i am right or wrong. I at first take 99% etanol and add it to 5 gm oil sample. Then heat it for 7-10 minutes and then add 1 ml 1% or 5% phenolphthalein indicators and carried out titration Against KOH. Then a blank titration is done. Volume of KOH = KOH required for the test - KOH for blank. Say KOH for Sample = 0.8 KOH for blank = 0.2 Volume of KOH = 0.6 I then use the following formula ACV = Molarity of KOH * Volume of KOH * Molecular weight of KOH / sample weight. In this i Don't need to neutralise the alcohol as i carried out a blank experiment.

Good video, Pls unit for acidity is missing.

Hi, do you know if I could use Isopropanol instead of Ethanol?

good video btw 👍

How to know whether the ethanol is dissolved or not because my solution always separated as ethanol and oil after i removed it from hot plate

or do we need to wait until the mixture is cooled down to room temp?

Thanku so much ma'am 🔥✨❤️

When the sample is prepared you are boiling it, but my experiment wants to see the effect of frying on acid value so is it possible to do it in a different way to prevent boiling of the sample?

Why don't you show the standardization of NaOH in this video?..isn't it necessary?

Please Ihave a question, why did you heat the ethanol with sample and what is the time required to heat

Why do we put an equal amount of alcohol and ether when determining or performing for acid value?

What is the maximum value of ffa for a good oil...?

Good day is there unit for the acid value ? due he did not write it

Thanks a lot..but i have a question, this method is also applicable to virgin coconut oil

What is unit for acid value, and you didn't also show the calculation of free fatty acid

Thanks a lot, Pls peovide FFA method & It's calculation

How to find expected Acid value ???

Whats the procedure for groundnut oil ?

thank you for this clarifying experiment, i have a question, you used 10 g of oil, bcs i don't have enough samples what if i used only 2 g of oil, do i need to divide all mixtures by 5? Please reply me

Thank you

Can you please provide a documented file or article of the procedure ?

Thanks for the video. A question though,what about orange peel oil!? What procedure is useful?

I really love your easy methods. Please help with this question. Based on this method , my expected acid value is 15-75. Will it be right to use 0.5g of sample and 50 ml of ethanol?

Hi. Im iranian chemist, why heat erlen before titration? Your erlen contain oil , it leads to increase acid value

hi is acid value depends upon the number of grams of fat taken. i take normally 1 gm of mustard oil to calculate ffa .what should be its range in that case

I did acid value today on hydrogenated vegetable oil as per USP method. United States pharmacopeia. They say to melt the sample (was in powder form) and add 100 ml of hot alcohol previously neutralized with NaOH, to phenolphthalein ts. Then add 1 ml of the indicator. How would you interpret this? Do I add the naoh to the alcohol first and then heat or do I add after heating? And the indicator after heating? Pls help. I think I messed up here somewhere so it didn't pass

Thank you so much mam

Thnks ❤

Thanks so much for sharing, we dissolve sample with solvent may be (hot ethanol) or a mixture of 96%ethanol and diethyether(1:1)...and heating the sample with solvents if necessary by gentl heating about 40°c.. Because high temperature destroy triglyceride and realise free fatty acid ..

Miss why are you adding phenopthline for twice?. Also requested share procedure for rancidity test with reference. Thanks.

Hi, does the mixture have to be heated until boil? if so, how long should i let it boil?

Can we use 0.5%phenopthalein indicator??For av determination.

Sir i have a question . Is there any machine available to check moisture for ghee?like the BR check machine .

Can we use methylene blue instead of phenolphthalein? Then what are the procedures?

Thanks a lot for sharing this very informative video. I have a question, can I replace EtOH 96% or 70% instead of 99%?

Thank you for this video. I want to ask, if we use KOH as the titrant, definitely the formula will will take molecular weight of KOH?

The calculation in description section is wrong! 56.1 is the molecular weight of KOH and since you've used NaOH so it should be 40.001. So the actual calculation should be Av= (40.001*normality of NaOH*volume of NaOH)/ Weight of the sample FFA(%oleic acid) = (28.2*Volume of NaOH*normality of NaOH)/weight

Hi. Where can we get the official copy of this method? is it available online?

Pls make a video on tannin in tea

After neutralizing ethanol just add to sample and titrate Why boiling??

hi, how do we know the "expected acid value" if let's say I do not know the profile of the oil I am about to test?

Kindly mention the proper reference of this recipe. Or any pdf or paper u have followed.

Please help me out, how do calculate FFA from acid value dealing with shea butter sample

How to calculate the acid number of a mixture of oil? If i want the total mixture of oil is 10 gram and i have 2 oil with diffent acid number. One is 0,1 and the other 4. How much of each of these oils? Thank you

Please tell me that the determination of Acid value with FFA is different?

In our laboratory we are using methanol instead of ethanol, but the results are nearly same, is it possible?

Thanks
