No, cooked rice will not turn dark blue with iodine solution. Iodine solution is commonly used to test for the presence of starch in a substance, as it will turn blue-black in the presence of starch. However, rice primarily contains carbohydrates in the form of starch, which is broken down during the cooking process, so there is little to no starch left in cooked rice to react with the iodine solution.
Potato, cornstarch, rice, or bread can turn blue-black with iodine solution due to the presence of starch.
The leaf turned black when iodine solution was placed on it because iodine reacts with starch present in the leaf, forming a dark blue-black complex. This color change is a common test used to detect the presence of starch in a leaf.
The mixture stopped turning the drops of iodine solution blue after 240 seconds due to the completion of the reaction between iodine and the other components in the mixture. Once all the iodine had reacted, there was no more available iodine to cause the blue color change.
The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
Potato, cornstarch, rice, or bread can turn blue-black with iodine solution due to the presence of starch.
it is a yellowish/orange colour but when iodine is present, than it will turn an dark-blue/black colour

The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
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.
Iodine solution turns blue/black
The endosperm will turn blue-black in color when iodine solution is applied, indicating the presence of starch.
The liquid used to test for starch is called iodine solution. Iodine solution turns a blue-black color in the presence of starch.
If iodine solution turns blue-black, it indicates the presence of starch. Iodine forms a complex with starch, resulting in the blue-black color.
