What else can I help you with?
What will happen to a leaf when you put iodine solution into it?
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
Why do you put iodine on onion not rhubarb?
Iodine is used to test for the presence of starch in a substance. Onions contain starch, which reacts with iodine to produce a blue-black color. Rhubarb does not contain a significant amount of starch, so it will not produce the same reaction with iodine.
What Reacts with iodine to form a blue color?
Starch reacts with iodine to form a blue/black color. This reaction is commonly used as a test for the presence of starch in a substance, such as in biology and chemistry experiments.
Would the iodine solution change colour when it is tested on a slice of bread?
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
Why do en leaves not turn blue backby iodine?
En leaves do not turn blue-black with iodine because they do not contain starch, which is what iodine reacts with to produce the characteristic color change. Starch is a carbohydrate produced by plants through photosynthesis, so leaves that do not contain starch will not show the blue-black color reaction with iodine.
What does iodine detect?
The iodine test is used to test for starch. It reacts with starch to produce a purple blackish color.

When starch reacts with iodine what color appears?
purple
What sugar react with iodine solution?
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.
What colour does idoine go if there is no starch present in a food?
If iodine is added to a food that does not contain starch, it will typically remain a brownish-yellow color. This is because iodine reacts with starch to produce a blue-black complex, but in the absence of starch, no such reaction occurs, and the iodine retains its original color.
What Reacts with iodine to form a blue color?
Starch reacts with iodine to form a blue/black color. This reaction is commonly used as a test for the presence of starch in a substance, such as in biology and chemistry experiments.
Would the iodine solution change colour when it is tested on a slice of bread?
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
Is it tru that iodine reacts with starch to give a red color?
No when you but iodine with sarch for example a potato the starch reacrs with the iodine and it turns black
Why do en leaves not turn blue backby iodine?

What color gives if starch reacts with iodine?
When iodine reacts with starch, the solution will turn a brownish colour.
Why does iodine react with sugar?
Iodine reacts with sugar due to a chemical reaction called iodine starch reaction. Iodine forms a complex with starch molecules, giving a characteristic blue-black color. As sugar molecules can also form a complex with iodine, they can interfere with the reaction, leading to a color change.
