the answer to tis would be iodine because it is uses in the method to test for presence of startch in a leaf
When starch is mixed with iodine solution in a test tube, a chemical reaction occurs that results in a color change. The iodine interacts with the helical structure of starch molecules, producing a dark blue or blue-black color. This reaction is commonly used as a test for the presence of starch in various substances.
The reaction between Lugol's solution (iodine) and starch forms a blue-black complex. Iodine molecules fit into the helical structure of starch molecules, producing this characteristic color change. This reaction is commonly used to test for the presence of starch in a solution.
Benedict's solution is used to test for glucose, turning from blue to orange-red in the presence of reducing sugars. Iodine solution is used to test for starch, producing a blue-black color in the presence of starch.
I2KI (iodine-potassium iodide) is commonly used as a starch indicator solution to test for the presence of starch in a sample. When I2KI is added to a substance containing starch, it turns blue-black in color. This reaction is often utilized in biology and chemistry experiments to detect the presence of starch.
Fehling A and B Benedict solution
The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
The chemical used to test for the presence of starch is iodine.
Iodine solution is the common chemical reagent used to test for the presence of starch. When iodine solution is added to a substance containing starch, it will turn from amber or yellow to a blue-black color if starch is present.
Iodine solution is used to test for starch because it reacts with starch molecules to form a dark blue or black color. This chemical reaction is significant in identifying the presence of starch because it provides a visible and easily recognizable indication of the presence of starch in a substance.
IKI solution is used to test for the presence of starch. Starch will turn blue-black in the presence of IKI solution, indicating a positive test result for the presence of starch.
I2KI (iodine/potassium iodide solution) is used to test for the presence of starch. In the presence of starch, the solution will turn blue-black due to the formation of a starch-iodine complex.

Oh, dude, the chemical test to confirm the presence of starch is the iodine test. You basically add iodine solution to your sample, and if it turns blue-black, like the color of a midnight sky, then congrats, you've got starch! It's like magic, but with science.
alcohol , iodine solution
The iodine test is used to test for the presence of starch. Iodine solution interacts with the starch molecules, causing a color change from brownish-yellow to blue or black.
