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
Which white powder turns blue-black in iodine solution?
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
What happens when iodine is added to carrot?
The colour of the iodine will turn from yellowish brown to dark blue
What is the product of the reaction between starch and iodine?
The product of the reaction between starch and iodine is a blue-black complex known as iodine-starch complex. This complex forms due to the iodine molecules inserting themselves into the helical structure of starch, creating this distinctive color change.
If Iodine turns black in the presence of starch what is the identity of the powder that turned black?
does not matter once the Powder has starch it turns black and the powder can be any color
What is the colour of starch after iodine has been added?
The color of starch after iodine has been added is deep blue to black.
Why did the leaf turn blue-black when iodine was added.?
The leaf turned blue-black when iodine was added because iodine reacts with starch, which is present in the leaf. This reaction forms a blue-black complex, indicating the presence of starch in the leaf.
What happens when iodine is added to a starch solution?
When iodine is added to a starch solution, the iodine molecules will interact with the starch molecules through a process called iodine-starch complex formation. This complex leads to a characteristic color change from the initial colorless solution to a dark blue-black color, indicating the presence of starch in the solution.
What color occurs when the indicator is added and starch is added?
When an indicator such as iodine is added to a solution containing starch, a blue-black color change occurs. This reaction is commonly used to detect the presence of starch, as the blue-black color is characteristic of this complex formed between the starch and iodine molecules.
When does iodine turn black when rice is added to iodine or iodine is added to rice?
When iodine is added to rice, it turns black when it comes in contact with starch. Starch is present in rice, so when iodine is added to rice, it reacts with the starch and forms a dark blue-black color. This reaction is often used to test for the presence of starch in foods.
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
Why if starch is present there is a blue-black colour?
The blue-black color seen when iodine is added to a solution containing starch is due to the formation of a complex between iodine and starch molecules. This complex is known as "iodine-starch complex," which results in the color change.
What colour does iodine turn when added to starch?
Iodine turns a dark blue or black color when added to starch. This reaction is often used as a test to detect the presence of starch in a solution.
What color develops when iodine solution is added to starch solution?
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.
What happen when starch add to iodine?
When starch is added to iodine, a chemical reaction occurs that results in the formation of a blue-black color. This color change is used as a test for the presence of starch in a substance. Starch molecules form a complex with iodine molecules, leading to the distinct blue-black color.
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 color does the presence of starch indicates?
The presence of starch is indicated by a blue-black color when iodine solution is added.
