WebIodine, with atomic symbol I, is a nonmetal that lies in group 17 of the periodic table, the halogens. The element iodine lies below bromine, above astatine, to the right of tellurium, and to the left of xenon. Its aqueous chemistry is similar to bromine’s. Iodine has an electronegativity of 2.66. The iodine atom has an electron configuration ... WebIodine: Iodides are weak reducing agents, as per their salts. Iodine is produced when they react with oxygen. These have a variety of antioxidant characteristics as well. Reducing sugars: Due to the presence of a free ketone group or a free aldehyde group, reducing sugars have a similar behaviour as reducing agents. Reducing sugars include all ...
WebThe presence of iodine in a weakly alkaline solution can be indicated by adding a few drops of a diluted solution of amylose (“starch”), leading to the typical blue colour. The colour disappears, if glucose is added to the solution. The active oxidizing agent in the reaction is not iodine itself but hypoiodous acid, HOI. The latter is ...
