Brownish.
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.
Iodine turns a blue-black color when starch is present. This is due to the formation of a starch-iodine complex, where the iodine molecules interact with the starch molecules causing the color change.
Starch turns a blue-black color when treated with a few drops of iodine solution. This color change occurs due to the formation of a complex between the starch molecules and the iodine ions.
Bread turns blue-black when iodine solution is added due to the presence of starch. The iodine reacts with the starch molecules in the bread, forming a complex that gives this characteristic color change.
Iodine turns blue-black in the presence of starch.
Iodine turns blue-black in the presence of starch.
It turns a dark purple/blue colour
It turns the iodine colour from brown to blue-black? This is because popcorn contains starch.
it is a yellowish/orange colour but when iodine is present, than it will turn an dark-blue/black colour
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.
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
BlackAns2:It is very unlikely that a ripe banana will have enough starch to turn iodine black. When iodine turns black, it is a positive test for the presence of starch.
As you know that iodine act as indicator for testing of starch so when a drop of iodine is added to starch it turns bluish black but when added to distilled water nothing happens except the colour of water which turns brown and its is the colour of iodine.
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.
Iodine turns a blue-black color when starch is present. This is due to the formation of a starch-iodine complex, where the iodine molecules interact with the starch molecules causing the color change.
Starch turns a blue-black color when treated with a few drops of iodine solution. This color change occurs due to the formation of a complex between the starch molecules and the iodine ions.
Iodine solution is commonly used to test for the presence of starch. When iodine solution is added to a substance containing starch, the mixture turns blue-black in color, indicating the presence of starch.
