Iodine is sensitive to light and can be easily photodegraded, which can affect the accuracy of the titration results. Keeping iodine in the dark helps to prevent its degradation and ensures more reliable titration measurements.
6H+ + IO3- + 5I- = 3I2 + 3H2O. In light this reaction occurs . So cannot occur this unwanted reaction, solution keep in dark.

Why do sample should be keep in dark place for 30minutes in determination of iodine value?
Samples are kept in the dark for 30 minutes in the determination of iodine value to prevent the oxidation of unsaturated fats by light. Exposure to light can cause the fats in the sample to undergo photooxidation, which can result in inaccurate measurement of the iodine value.
How do they store iodine?
Iodine is commonly stored in a cool, dark, and dry place in a tightly sealed container. It should be kept away from heat sources and moisture to prevent degradation and maintain its potency. Handling should be done with care as iodine can stain surfaces and emit potentially harmful vapors.
What is idometric titration?
Idiometric titration is a type of titration where the titrant is also the indicator. This method is used when there are no suitable indicators available for a particular titration. The end point is determined by measuring the potential difference between the two electrodes in the cell.
What is the control variable in titration?
In a titration experiment, the control variable is the volume of the titrant added to the analyte solution at each step. This volume should be kept consistent throughout the experiment to ensure accurate and reliable results.
What precaution should be taken in iodine solution?
Iodine solution is toxic if ingested, so it should be kept out of reach of children and pets. It should be stored in a tightly closed container, away from heat and light. When using iodine solution, avoid contact with skin and eyes, and work in a well-ventilated area to prevent inhalation of fumes.
Who kept learning alive in Europe during the Dark Ages?

When was Kept in the Dark created?
Kept in the Dark was created in 1882.
What would you need if I am doing a science project about putting one plant in the dark inside and one plant outside in the light?
The project is on necessity of light for photosynthesis. Therefore, iodine solution is needd to test the formation of starch in the plant kept in light by photosynthesis. The plant kept in dark will show the absence of starch meaning there by no photosynthesis has taken place in dark.
Why are bats kept in dark cages?
in the forest the come out in the dark so they are kept in dark cages
