The brown color in the bottle of pure HI is likely due to the slow decomposition of the hydrogen iodide (HI) into iodine (I2) and hydrogen gas (H2). This reaction can be catalyzed by light, heat, or impurities in the HI solution. The formation of iodine can give the solution a brown color.

Why silver bromide is kept in brown bottle?
Silver bromide is kept in a brown bottle to protect it from light exposure. Light can cause silver bromide to degrade, affecting its sensitivity to light and ruining its performance as a light-sensitive material in photographic applications. The brown color of the bottle helps to block out damaging light rays and prevent this degradation from occurring.
Why is h2o2 kept in colour bottle?
Hydrogen peroxide (H2O2) is kept in a colored bottle to protect it from light exposure. Light can trigger a chemical reaction that can break down hydrogen peroxide into water and oxygen, reducing its effectiveness. Storing it in a colored bottle helps maintain its potency and stability.
Why a tightly capped bottle full of water is kept in the open sunlight tiny bubbles are formed all around the bottle?
When a tightly capped bottle of water is kept in the open sunlight, it heats up and the water inside starts to evaporate. The evaporation process releases gases trapped in the water, creating bubbles around the bottle. The heat from the sunlight accelerates this process.
Why chloroform kept in dark brown bottle?
Chloroform in the presence of air gets oxidised to phosgene. Phosgene is carbonyl chloride & is represented as COCl2. To prevent the formation of phosgene, chloroform is stored in dark colored bottles.This is represented as CHCl3 + 1/2 O2---->COCl2 + HCl.
Can acetone be kept in plastic bottle?
Acetone can be kept in a plastic bottle made from high-density polyethylene (HDPE) or polyethylene terephthalate (PET) since these materials are resistant to acetone. Avoid storing acetone in bottles made from other types of plastic, as it may cause the plastic to degrade and leak.
Why silver bromide is kept in brown bottle?

Why do we get dew on the surface of a cold soft drink bottle kept in air?
Moisture in the air condenses on the cold bottle. If the air is dry, there will be no dew on the bottle.
Why do we get dew on the surface of a cold soft drink bottle kept in open air?
Moisture in the air condenses on the cold bottle. If the air is dry, there will be no dew on the bottle.
Why are some reagent bottle colored?
Reagent bottles are colored to protect light-sensitive chemicals or compounds from being degraded by exposure to light. The colored glass helps to block certain wavelengths of light that can cause chemical reactions or decomposition of the reagent inside the bottle.
