then starch is not present...
Iodine does not react with sugar, it reacts with starch.
Iodine will will not react with hydroelectric acid
the iodine will react with carbohydrate to give different color .
Yes. Rubidium is an alkali metal in the sodium group. It will react with iodine to form rubidium iodide:- 2Rb+ I2 -> 2RbI
It's very likely that Iodine will react with plant products, since Iodine reacts with starch. Negative controls (glucose, water, and protein) could be used to verify the result.
Iodine does not react with sugar, it reacts with starch.
if you cover a boiled leaf in iodine you can see how much starch is in the leaf
Iodine will will not react with hydroelectric acid
To determine the location of starch in a leaf, one can examine it under the microscope and apply one small drop of iodine to the leaf. The parts of the leaf that turn purple contain starch.
By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not. The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.
to destarch a leaf, you have to have two things first. A leaf and a bottle of iodine solution. You need iodine solution to separate the sugar molecules (glucose molecules) to the leaf itself, on the upper epidermis of a leaf, on the cuticle.
no
the iodine will react with carbohydrate to give different color .
No. If it did, it'd spontaneously boil, fume of burn in its container.
the iodine stayed orange because the starch wasn't present
Yes
