Please note the following correction: in the table at 5:13, the answer to the final calculation, the mass of vitamin C in milligrams per gram of food, should be 0.11 (not 0.37 as stated in the table).

very informative. cleared many doubts.
You literally saved my grades, TYSM
im not here by choice
in this case the mass will be in mg or gr per fruit gr???
you saved my life thank you <3
do you mean the more drops of iodine mean more vitamin c in the food sample?
hi im so confused
Nice video and nice scientist
Pot more information
whats the difference between this calibration method and titration method?
How do we analyze or measure vitamins in supplement products like tablets or pills? To know if we really get what we pay for.
hello please can you tell me why are we going to take 0.11 and not the one which already there thank you
How can vitamin C be measured without identifying it? You have no idea what vitamin C to be able to "measure" it. This was just a chemical reaction. It seems no one on the internet can identify any vitamins, yet claim they can measure them? Makes no sense lol
Crap. That's not a vitamin C measurements. All man theories. Not real
Hi, thanks for the helpful guide. If I used a vitamin c tablet that contains corn starch in my experiment, will that affect the results?
By any chance is there a way I can do this with processed juices? If so, how do i measure its vitamin c using this experiment instead of fruit?
Hi, how do you prepare the sample if I'm using an orange? Do I extract the juice or what?
Hello, great video. Was wondering what concentration of iodine you used, and why does it matter?
Hello! Can I use all-purpose flour instead of corn flour? Will the results change?
Hi, can i use potato starch as a replacement for corn starch?
And can I use DCPIP instead of starch and iodine?
Hi, can I use this method to investigate the effects of oxidation on the content of vitamin C as the research question of a science paper?
If I use raw potato, it won´t cross reaction with starch since potato has starch?. TKU for you answer.
hey i have to find vitamin a and vitamin c content in few frozen vegetables and fruits can you pleasee tell me in which form i should freeze them? like okra should i freeze it in raw form??? and what about corn and peas??
Hello, Can I substitute the corn flour with cornstarch? Or it is the same?
hello, and also can you explain me why is necessary the use of starch? btw thanks for the video
hi, I am a little confused, where did you get the Mass of vitamin C in milligrams per gram of food = 0.37 mg/g in minute 5:13. Because there is says
NxI=O
so 0.36 x 0.31=0.11
so its equal to 0.11 an not 0.37
Hello, thanks for sharing. I am trying the analyze the vitamine C in black peppers. I just wonder if there is any extraction before analysing or just powedering the black peppers? Thanks in advance for your answer..
what are the reactions happening???
Hi, what is the concentration of the iodine that you used?
Hi, I want to use this in a scientific study. Can this procedure be used?
I'm in!!!!
