Iodine changes color when I contact with starch
The color of solid iodine is a dark purple.
There is a dark blue colour when iodine is added to starch instead of a yellow sort of colour when iodine is added to a substance without starch.
purple.
Violet / Purple
Probably purple.
I stands for iodine. Iodine is a halogen. It is grey in colour.
The iodine clock reaction is based around the colour change that occurs when iodine reacts with starch, turning from a clear colour to a black-blue colour." (2) The starch allows the iodine and the iodide ions to bond, forming a triodide ion. I2(aq) + I−(aq) ⇌ I3−(aq) In this reaction, iodide is viewed as a base, and iodine is viewed as an acid. The iodine is a ligand and is surrounded by the starch, as for the colour change, that is due to the iodine absorbing all light wavelengths corresponding to colours, hence not letting any through, so what you are seeing when the solution is black, is the absence of light and colour alltogether,
Iodine becomes purplish blue while mixed with water.
give reasons for the colour change of the leaf when iodine is added to it?
cause iodine(brown) stains the rice
The colour of the iodine will turn from yellowish brown to dark blue
the iodine does not turn the starch black."The iodine clock reaction is based around the colour change that occurs when iodine reacts with starch, turning from a clear colour to a black-blue colour."

it is violet and lustrous
deep purple
Brownish.
Purple !! :) x
Brown/Orange/Yellowy
Only you know the answer... :)
Iodine
Blue-Black
The colour of iodine molecule I2 is due to n-> sigma anti bonding electronic transition. It changes its colour when it is adsorbed on starch or reduced to I-
When iodine reacts with starch, the solution will turn a brownish colour.
It turns the iodine colour from brown to blue-black? This is because popcorn contains starch.
because the molecules of iodine absorbs red and violet radiations and then emit them
