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.
What would happen if you did an experiment in which the iodine solution was placed in the Baggie and the starch was in the beaker?
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
What would happen if you added three drops of iodine to an onion?
I did this experiment and after a while the onion cell became incredibly easier to see.
What is the Conclusion of testing iodine and starch in expariment?
The conclusion of testing iodine and starch in an experiment is typically that a blue-black color change indicates the presence of starch in the solution. This is due to the formation of a complex between iodine and starch molecules. The test can be used as a qualitative test for detecting the presence of starch in a sample.
What is the common name for iodine?
The common name for iodine is iodine.

What color does iodine turn when you do an experiment for starch?
dark blue - purple
Why did each of the solutions turn iodine blue black at the start of the experiment?
The solutions turned iodine blue-black at the start of the experiment due to the formation of a complex between iodine and starch. Iodine interacts with the helical structure of starch molecules, resulting in a color change that indicates the presence of starch in the solution. This reaction is a classic test for starch, demonstrating its presence through the formation of the blue-black complex.
How is iodine important in living things?
iodine is test for starch it can also help us do experiment and also to check is carbon diocide is presence and it only works on plant which have die
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.

Is it necassary to take full bath after intercourse?
No.
Is this necassary to remove hips hair in Islam?
no
Are braces necassary?
depends on the person teeth
What performs necassary activities for the cell?
The Nucleus
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.
What are some little known facts about iodine?
Iodine is used in practical experiments such as the onion cell experiment. Iodine will help make the cells visible. Iodine, should it be spilt on skin, can stain skin and will take quite some time to wash off.
