Why is hydrogen peroxide kept in coloured bottles?

Question

Answer

Hydrogen peroxide (H2O2),  is kept in colour botel to prevent it from being thermal decompose.  it's too reactive so that decomposed much more easily by sunlight.

Answer

Hydrogen Peroxide isa highly reactive metal which can easily react with heat and light so that H2Ocan be produced......therefore it is kept in coloured bottels so that light couldn't be passed in......!!!!!
hope its a satisfactory ans...!!!

Answer

Introduction:
Hydrogen peroxide (H2O2) is a common household disinfectant and cleaning agent. It is a pale blue liquid with strong oxidizing properties. To ensure its stability and effectiveness, hydrogen peroxide is usually kept in colored bottles, typically brown or dark-colored glass.

Protection from Light:
One of the primary reasons for storing hydrogen peroxide in colored bottles is to protect it from light. Exposure to light can lead to the decomposition of hydrogen peroxide, rendering it ineffective. Colored bottles act as a barrier, preventing the entry of light and maintaining the stability of the solution.

Ultraviolet Light:
Ultraviolet (UV) light, which is present in sunlight and artificial light sources, can accelerate the decomposition of hydrogen peroxide. The energy from UV light can break down the peroxide molecule, leading to the formation of water (H2O) and oxygen gas (O2). This decomposition process can occur more rapidly in the presence of certain catalysts, such as transition metals. By storing hydrogen peroxide in colored bottles, the harmful effects of UV light can be minimized.

Brown or Dark-Colored Glass:
Brown or dark-colored glass is commonly used for storing hydrogen peroxide due to its ability to absorb UV light. The dark coloration of the glass reduces the transmission of UV radiation, providing an additional layer of protection to the hydrogen peroxide solution. This helps to maintain the stability and potency of the product for a longer period.

Preventing Contamination:
Besides protecting hydrogen peroxide from light, colored bottles also serve as a barrier against contamination. The presence of contaminants, such as dust, dirt, or microorganisms, can degrade the quality and effectiveness of hydrogen peroxide. By storing it in colored bottles, the risk of external contaminants entering the solution is reduced.

Summary:
In summary, hydrogen peroxide is kept in colored bottles, typically brown or dark-colored glass, to protect it from light, especially UV radiation. The colored glass acts as a barrier, preventing light-induced decomposition and maintaining the stability and effectiveness of the solution. Additionally, colored bottles help to prevent contamination, preserving the quality of hydrogen peroxide.
