When sugar and iodine are mixed, the iodine will turn purple or black due to a reaction with the starch that is naturally present in sugar. This color change is commonly used as a simple test for the presence of starch.
Mixing powdered sugar and iodine will not have any significant reaction, as iodine is not a strong enough oxidizing agent to react with the sugar. The two substances will likely remain as separate particles with the iodine coloring the sugar.
When maltose, a reducing sugar, is mixed with iodine, a redox indicator, the iodine molecules will bind to the open aldehyde groups of the maltose molecules creating a blue-black color. This is a common test for the presence of reducing sugars like maltose.
When iodine and borax are mixed, they do not react chemically. Both substances will remain as separate entities in the mixture. Iodine is a purple-black solid, while borax is a white crystalline powder.
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
When citric acid and iodine are mixed, they react to form iodine citrate. This reaction results in the formation of a pale yellow precipitate.
doesn't create gold, turns bluish though
When sugar and iodine are mixed together, the iodine will not react with the sugar. The iodine may simply dissolve into the sugar, giving it a purplish color. This reaction is purely physical and does not involve a chemical change.
Yes, sugar does not turn blue when mixed with iodine. Iodine reacts with starch, turning it into a blue-black color. Sugar does not contain starch, so it will not have a reaction with iodine in this way.
it does not turn blue when mixed with iodine. I don't think there is a colour change.
It turns clear and then turns to a dark blueish purple.It would be considered as a chemical reaction.It also takes a while for it to go though this process, but it's worth it.Nora (:

The sugar disinigrates and is part of the water
I am not quite sure what happens when corn starch and iodine are mixed but when corn starch, iodine and water are mixed, it creates a purple solution. The darkness of the colour mostly depends on the iodine. Without the starch with iodine and water, it is deep yellow or brown.
When citric acid and iodine are mixed, they react to form iodine citrate. This reaction results in the formation of a pale yellow precipitate.
