What colour should the leaf turn when iodine is added?
The leaf should turn blue-black when iodine is added, indicating the presence of starch.
What colour does the leaf turn once iodine is added and is no starch?
When iodine is added to a leaf with no starch, the leaf will remain its original color (usually green). Iodine reacts with starch molecules, turning the leaf blue-black if starch is present.
What will happen to a leaf when you put iodine solution into it?
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.
What did you see on the leaf in the test tube when testing for starch?

What color does a iodine turn when there is no starch in a leaf?
Iodine turns a yellow-brown color when there is no starch present in a leaf. This color change indicates the absence of starch, which is detected by the iodine as it interacts with the leaf's compounds.

Why did the leaf turn blue black when iodine was added in the starch test?
The leaf turned blue-black in the starch test because iodine forms a complex with starch molecules, resulting in the blue-black color change. This color change indicates the presence of starch in the leaf tissue.
What is the color of the leaf at the end of the experiment that test for starch?
the color of the leaf become brown-black after the iodine solution was added.
What color does a iodine turn when there is no starch in a leaf?
Iodine turns a yellow-brown color when there is no starch present in a leaf. This color change indicates the absence of starch, which is detected by the iodine as it interacts with the leaf's compounds.
What is the role of iodine in testing a leaf for starch?
A hot bath of ethanol decolorizes the leaf by washing out the chlorophyll. If the leaf is not decolorized, you cannot see the blue-black stain that results from the iodine reacting with the starch.
Why do green leaves turn blue black when iodine is added?
because the leaves have photosynthesized- glucose is produced. therefore, the excess glucose is converted to starch. The starch is then stored in the leaf-starch is what causes the "green" leaf to turn blue black, as iodine turns blue-black when it reacts with starch.:P
What effect the iodine solution have on a leaf?
Iodine solution can test for the presence of starch in a leaf. When iodine solution is applied to a leaf, it will turn blue-black in areas where starch is present. This is because iodine reacts with starch to form a bluish-black complex.
Why did each of the solutions turn iodine blueblack at the start of the experiments?
The presence of starch in the solutions caused them to turn iodine blue-black at the start of the experiments. Iodine forms a dark blue-black complex when it interacts with starch molecules, making it a commonly used indicator to detect the presence of starch in solutions.
Why does a sugar solution turn brown when Iodine is added?
Because Iodine is a brown element.
