purple
No when you but iodine with sarch for example a potato the starch reacrs with the iodine and it turns black
The iodine test is used to test for starch. It reacts with starch to produce a purple blackish 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.
When iodine reacts with starch, the solution will turn a brownish colour.
When iodine reacts with starch, it forms a complex known as the starch-iodine complex. This complex results in a deep blue or purple color, which is easily visible. The color change occurs due to the way iodine molecules interact and bond with the long chains of glucose molecules in the starch structure.
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.
Starch molecules react with iodine to produce a blue-black color. This reaction is commonly used as a test for the presence of starch in a substance.
If the endosperm contains starch, it will turn blue-black in the presence of iodine solution. This color change indicates the presence of starch in the endosperm, as iodine reacts with starch to form a starch-iodine complex, resulting in the blue-black color.
Iodine turns colorless when it reacts with starch molecules. This reaction forms a complex between iodine and starch, which results in the loss of the characteristic purple color of iodine. This color change is commonly used as an indicator for the presence of starch in a solution.
Iodine reacts with starch to form a dark blue or black color. This is used as a common test to detect the presence of starch in a substance.
They test for carbohydrates. The Iodine reagent tests for starch. The Benedict's reagent tests for small sugars. Most carbohydrates are are made of sugar, and starch is a type of carbohydrate.
The purpose of the iodine test is to detect the presence of starch. Iodine reacts with starch molecules and forms a blue-black color, allowing for visual identification of the presence of starch in a sample.
