Why avoid the light in determine iodine value experiment?

Avoiding light in the determination of iodine value is important because iodine is light-sensitive and can react with light, leading to inaccurate results. Light exposure can cause the iodine to degrade or evaporate, which would affect the measurement of the iodine value. By conducting the experiment in a dark environment, you ensure the accuracy and reliability of the iodine value determination.

Why iodine place in dark color bottles?

Iodine is stored in dark-colored bottles to protect it from light, which can degrade the iodine molecules and reduce its effectiveness. Light exposure can cause iodine to evaporate or break down chemically, compromising its stability and potency. Keeping iodine in dark bottles helps to maintain its quality and extend its shelf life.

What effect does iodine have when added directly to a leaf in an experiment?

Iodine added directly to a leaf in an experiment can be used to test for the presence of starch. If the leaf turns blue-black, it indicates that starch is present in the leaf, as iodine reacts with starch molecules to produce this color change. This is commonly used in biology experiments to show the photosynthesis process in plants.
