When flour is added with iodine, the mixture usually turns a dark purple or black color due to the interaction between the starches in the flour and the iodine. This color change is commonly used as a test to detect the presence of starch in a substance.
When iodine is added to flour, it forms a complex with the starch molecules in the flour, creating a blue-black color. This reaction is often used as a test to detect the presence of starch in a sample.
When iodine is mixed with flour, it can form a complex chemical reaction resulting in a bluish-black color. This reaction occurs due to the starch content in flour interacting with iodine. This color change can be used as an indicator to detect the presence of starch in a given substance.
Egg white turns a blue-black color when iodine is added due to the reaction between the iodine and the proteins present in the egg white.
Cells will appear blue or purple after iodine is added to the slide. The iodine reacts with starch in the cells, resulting in a color change that helps to visualize the cellular structures.
The color of starch after iodine has been added is deep blue to black.

Blue .
Cells will appear blue or purple after iodine is added to the slide. The iodine reacts with starch in the cells, resulting in a color change that helps to visualize the cellular structures.
The color of starch after iodine has been added is deep blue to black.
The colour of the iodine will turn from yellowish brown to dark blue
A dark blue/black color develops when iodine solution is added to starch solution. This color change occurs due to the formation of a starch-iodine complex, where the iodine molecules interact with the helical structure of the starch molecules, resulting in the blue/black color.
When Lugol's iodine is added to dextrin, the color change is typically a blue-black coloration. This reaction is often used as a test for the presence of dextrin in a substance.
iodine is soluble in CHCl3. Liquid become purple in color.
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.
