Iodine solution reacts with light to undergo a photodecomposition reaction and therefore must be stored in amber bottles to minimise the amount of light that the solution is exposed to. If stored in a clear bottle it will gradually break down as the iodide ions are gradually converted to iodine and the solution turns a yellowish colour.

How do you prepare iodine solution?
To prepare iodine solution, dissolve iodine crystals in a mixture of water and potassium iodide (KI). The ratio of iodine to KI will determine the concentration of the solution. The solution should be stored in a dark bottle to prevent degradation from light exposure.
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.
Why does Wijs solution need to be stored in the dark for 30minutes?
The Wijs solution contains iodine, which is light-sensitive and can undergo photodegradation upon exposure to light. Storing it in the dark helps to prevent this degradation and ensures the stability and accuracy of the solution for the iodine value determination.

Why iodine solution is stored in coloured bottles?
Medicine and perfume are normally made up of chemical compounds. Exposure to light can often provide enough energy to breakdown these compounds, changing the way they work and smell. Dark colored bottles help protect these compounds and allow them to remain stable for a longer period of time.
What is a reagent that stains the stored food of a green algae black?
Lugol's solution is commonly used to stain the stored food of green algae black. Lugol's solution contains iodine, which reacts with starch in the stored food of algae, turning it black or blue-black upon staining.
Where is iodine stored in the body?
Iodine is stored throughout the body, including in the muscles and bones. The thyroid gland concentrates the iodine from throughout the body; it is essential for proper growth and development.
Where iodine is stored?
Iodine is primarily stored in the thyroid gland in the form of thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3). It is also found in trace amounts in other tissues, such as the salivary glands, stomach lining, and mammary glands.
Where is iodine stored in humans body?
Iodine is primarily stored in the thyroid gland in the human body. It is used by the thyroid gland to produce thyroid hormones that regulate metabolism, growth, and energy production. Any excess iodine that is not used by the body is excreted through urine.
Does iodine tincture expire and if so, what is the shelf life of iodine tincture?
Yes, iodine tincture does expire. The shelf life of iodine tincture is typically around 3 to 5 years if stored properly in a cool, dark place.
What is used to store the substances that decomposes when exposed to sunlight?
for liquids it is stored in coloured bottles.
Why H2O2 is stored in coloured wax?
Hydrogen peroxide (H2O2) is light-sensitive and can decompose when exposed to light. Storing it in colored wax helps to block out light and prevent this decomposition. The colored wax acts as a barrier to light, preserving the integrity and effectiveness of the hydrogen peroxide solution.
