The iodine flask is used for the iodine assay because it allows for the controlled reaction between iodine and thiosulfate. The shape of the flask ensures uniform mixing and minimizes loss of iodine vapor. This setup helps in accurately determining the concentration of iodine in a solution.

Why do you use external indicator in diazotization titration?
external indicator is required in diazotization as to observe the end point of the reaction. internal indicators cannot give the endpoint because they may form complexes which may cause hindrance. for example, in the assay of sulfa drugs, iodine-starch paste is used as external indicator, because if we add iodine paste in the conical flask it will react with the reactants and give the blue-black coloration in the beginning of the actions, which will not tell the end point of the reaction. instead, the iodine-starch paste is applied in a paper, and the compound from the burette is added in small quantities into the sulfa drug solution, and after every few milliliters a drop of solution from the conical flask is dropped on the iodine-starch paste, when there is sudden change in colour, the addition from the burette is stopped. and observations are made.
Do you use titrant in conical flask?
yes we use titrant in the conical flask ,this is because titrant is a solution we use in burrete for titration in this process we titrant the solution in the conical flask along with an indicator
What Scientist who use S shaped flask?
Louis Pasteur, a French chemist, popularized the use of the S-shaped flask in his experiments to disprove the idea of spontaneous generation. The S-shaped flask allowed air to enter the flask, preventing contamination from airborne microorganisms while still allowing for the exchange of gases.
What can you use in place of iodine?
You can use iodized salt, sea vegetables (like nori or kombu), cod, fish, milk, yogurt, and eggs as alternative sources of iodine if you are unable to use iodine itself.

How do you get pure dry iodine from a mixture of iodine and sand.?
Well every school kid knows about the 'cold finger' separation technique. Iodine changes from a solid straight to a gas when heated. It sublimes. So heat the sand/iodine mixture in a pyrex tube or flask which has a 'cold finger' inserted. The hot iodine gas will rise, hit the cold finger and form pure solid iodine crystals on the cold finger. Collect from the finger. This really is bog standard school kid chemistry.
What is the use of the flask in the laboratory?

Can you use betadine if you are allergic to iodine?
You should not use Betadine if a patient is allergic to iodine. Betadine contains approximately 1% iodine, which could be enough to cause an allergic reaction.
Could you use iodine instead of methyl blue?
It depends of the reason you are applying anyone of them on your skin. But there are new antiseptic drugs today which is safer and more effective. For simple wounds, both are efficient. Iodine is not indicated for people with hyperthyroidism .
