What is the reaction that occurs when iodine comes into contact with starch?
When iodine comes into contact with starch, a chemical reaction occurs that results in the formation of a dark blue or black color. This reaction is used as a test to detect the presence of starch in a substance.
Does iodine turn blue?
Iodine turns blue in the presence of starch
What happen when iodine reach coleus leaf?
When iodine comes into contact with a coleus leaf, it can be used to visualize starch. Iodine solution turns dark blue or black in the presence of starch, allowing you to see where starch is concentrated on the leaf. This reaction is commonly used in biology experiments to demonstrate the presence of starch in plant tissues.
What is iodine used to find?
Iodine is used to find the presence of starch. When iodine comes in contact with starch, it forms a blue-black complex, which is used in chemical tests to detect the presence of starch in various substances.
What nutrient are you testing for if you use iodine?
Carbohydrates, especially starch, which is a polysaccharide carbohydrate. Starch turns deep purple when tested with iodine.

What is the chemical used to test for the presence of starch?
The chemical used to test for the presence of starch is iodine.
What colors does iodine turn and what does it mean?
Iodine turns a blue-black color when it comes in contact with starch. This color change indicates the presence of starch, making iodine a common reagent for detecting the presence of starch in various substances.
Which white powder turns black when it touches iodine?
Starch is a white powder that turns black when it comes in contact with iodine. This reaction is often used as a simple test for the presence of starch in a substance.
HOW DO THE RESULTS OF THE IODINE TEST INDICATED THAT HYDROLYSIS OF STARCH OCCURRED?
An iodine solution turns a purplish-black if it comes into contact with the presence of a starch molecule. This reaction can take place at very minute concentrations of starch.
