When we rinse the stopper with water, does the water mix with the solution or we rinse the stopper in the sink

Thanks for watching, Daniel. We should rinse with 15 ml potassium iodide solution and pour the rinsate in the flask. Potassium iodide dissolves all Iodine fumes those are trying to escape through the gaps of stopper & neck. This ensures accuracy in the Iodine value measurements.

Sir can iodine value be used for triple bond unsaturated compound? Or we use this only for double bond unsaturated compound? Please tell.
@bhushansong2 жыл бұрын
@@Learner_being it is used for double bonds as they are commonly found in veg oils. I am not sure about its application in triple bond determination

Sir for this experiment we use Iodine monochloride or Wij's solution
@bhushansong Жыл бұрын
Thank you Ramdas. I've been using Iodine monochloride. It is corrosive and needs to be handled carefully (mask, gloves and glasses etc are advisable)

What is the concentration of KI solution? Does it really matter in the experiment?
@bhushansong Жыл бұрын
Many thanks Pola. A 10-15% w/v Aq KI solution would be sufficient. Purpose is to trap all Iodine fumes escaping from the gap of stopper & iodine flask.

Why ccl4 used? Why solution kept for only 30 min ?
@bhushansong2 жыл бұрын
CCl4 or chloroform acts as diluent, it also provides a common medium for the reactants to react. (or else, oil will float on the water and cannot react) Thirty minutes is the maximum time required for I-Cl to bind with the double bonds of oil. It ensures that binding is complete (for 1 g of oil).

Why are you use 0.1 M sodium thiosulfate
@bhushansong3 жыл бұрын
Na2S2O3 sodium thiosulphate (one of the few stable reducing agents) converts (reduces) iodine to iodide form. Na2S2O3 first reacts with iodine before iodine (I2) can form a complex with starch to give (blue-black color). Once all thiosulfate is utilized excess iodine now forms a complex with starch. This helps us to get accurate end point
