Hint: If a chemical compound is very reenergetic as soon as it is exposed to light or if a chemical compound is exceptionally sensitive in the direction of warm and humidity and also can conveniently be decreated, then in order to protect its chemical properties, we have to keep them in a dark or colored bottle. A colored bottle will certainly aid the chemical compound to prevent the light, warm, humidity, and also various other determinants that can result in the decomplace of the compound.Complete action by step answer:A peroxide molecule is identified as a molecule in which an oxygen – oxygen single bond is current (recognized as peroxide linkage). Hydrogen peroxide is a chemical compound which is written of hydrogen and oxygen atoms. The molecular formula of hydrogen peroxide is $H_2O_2$. The chemical structure of a hydrogen peroxide molecule is given below:The oxygen-oxygen bond is the peroxide linkage (shown above) and also one hydrogen atom is over the airplane (solid dark bond) of oxygen – oxygen bond and also the other one is listed below the aircraft (broken bond).Hydrogen peroxide, a liquid compound, is the most basic form of all peroxides and also it has a significant oxidizing power and it is widely supplied as an oxidizer. Hydrogen peroxide is expected to be a small bit more viscous than water.Hydrogen peroxide is highly reenergetic and also its chemistry is overcame by the oxygen – oxygen bond (peroxide bond) which can conveniently be broken in existence of light or warm. Due to the presence of this peroxide bond, it is thermodynamically unsecure and also can quickly be decreated right into water and oxygen in visibility of light. The decomposition reactivity of hydrogen peroxide is provided below:$2H_2O_2 o 2H_2O + O_2$Therefore, if we store hydrogen peroxide in a normal glass bottle, then it will be exposed to light extremely conveniently and will be dewritten into water and oxygen. By this process of decomposition, hydrogen peroxide will have the ability to evapoprice as oxygen gas and also all its chemical properties will certainly be shed. Hence, hydrogen peroxide is stored in a colored (mainly brvery own colored bottle) bottle in order to nullify its decomposition and also protect its chemical properties.Apart from that, hydrogen peroxide deserve to easily react with alkali metal ions ( Na ^ + , K ^ + etc.). A normal glass bottle has many kind of alkali steels residues which may easily react with hydrogen peroxide if we save it in a constant glass bottle. In order to protect against this unwanted interactivity, the consistent glass bottles are avoided to save hydrogen peroxide. So, if we summarize, then to protect the hydrogen peroxide from light, heat, humidity, and alkali metal ions and also to save its chemical properties intact, hydrogen peroxide is retained in colored bottles.Note: The peroxide link provides the hydrogen peroxide exceptionally reenergetic in the direction of light. So, a very darker colored bottle (dark brown) is supplied to store hydrogen peroxide so that light cannot pass with the bottle and also the decomposition of hydrogen peroxide might be avoided.
