Thanks for your wonderful and passionate video. It's really useful for my work. I wonder some point that could you explain for me, please. 1. Why we certain use Carbon Tetrachloride in this experiment. Can you explain in detail the reason why you use Carbon Tetrechloride? Can I replace it by other substane? 2. I wonder if you put Potassium Iodide crystal around the stopped? Why don't we use the solution of Potassium Iodide? 3. In the phase that you pour distlled water into the flask, you titrate the flask with Sodium Thiosulfate until the yellow is lighter before you add the starch solution in the flask. So I wonder the reason why you must to titration before adding the starch solution. Is there any theory in this phase? I really want to know. I truly appriciate your support and I am looking forward to hearing from you. Many thanks

1. During titration, iodine flask should've been covered with the stopper throughout in order to avoid the escape of iodine gas. 2. calculation should've shown the units also 3. It should've been 126.9 g/mol, since that is the molecular weight of iodine.
@daniellekeller371 Жыл бұрын
Regarding 3.: Yes, but you have to divide by 10 to get the correct unit for the IV, which is g(I2)/100g(fat). It would have been obvious, if the correct units were used in the video.

@MicroChemsExperiments3 жыл бұрын
Ekin Gursoy, Thanks for your comment. Actually, when Wij's solution is added, it reacts with Iodine present in the sample to form slightly volatile compound. If we left open then loss of iodine may occur. That's why we keep the flask closed immediately after adding carbon tetrachloride and Wij's solution. Other two references for this test are: IS-548 and FASSAI MAnual.
