Yes, astatine can react with sodium iodine solution to form sodium astatide and iodine gas. This reaction is a displacement reaction where astatine displaces iodine from the sodium iodine solution.
Iodine and lithium bromide do not react with each other. However, iodine can form a complex with lithium ions in a solution containing lithium bromide.
Iodine is not reactive with potassium chloride in an aqueous solution because iodine is less reactive than chlorine. Chlorine is more likely to react with potassium to form potassium chloride, leaving the iodine unreacted.
The acid value of iodine solution represents the amount of free iodine present in the solution, which is a measure of its ability to oxidize or react with other substances. It is typically expressed in terms of grams of iodine per 100 milliliters of solution.
Iodine does not directly react with acids. However, when iodine is added to an acid solution, it can form hypoiodous acid (HOI) which is a weak acid. This reaction can be used in analytical chemistry to detect the presence of iodine.
I'd say NO: I never would expect it, nor having heard of and can't think why it could be yes.
Iodine solution typically reacts with polysaccharides, such as starch, to produce a blue-black color. This reaction occurs because iodine molecules fit into the helical structure of starch. Simple sugars, like glucose and sucrose, do not react with iodine and will not produce a color change. Therefore, it is primarily starch that is tested for using iodine solution in laboratory settings.
Iodine will will not react with hydroelectric acid
An aqueous solution of iodine (I₂) will not react with an aqueous solution of potassium bromide (KBr) because iodine is less reactive than bromine in terms of oxidation potential. In this case, iodine cannot oxidize bromide ions (Br⁻) to bromine (Br₂), as bromide is a stronger reducing agent. Therefore, no reaction occurs between the two solutions.
Cellulose tests negative with iodine solution. Iodine is used to test for the presence of starch, which forms a blue-black complex with iodine. Since cellulose is a polysaccharide but not a starch, it does not react with iodine in this way and remains colorless.
Because it didn't react with the iodine, i don't know
