Answer

Why Hydrogen Peroxide is Kept in Coloured Bottles?

Hydrogen peroxide (H2O2) is a colourless liquid that is used as a bleaching agent, disinfectant, and oxidizer. It is a very unstable compound that easily decomposes into water and oxygen gas. Due to its unstable nature, it can react with many substances and can be easily degraded by light. Therefore, it is usually stored in coloured bottles to protect it from light and maintain its stability.

Reasons for Storing Hydrogen Peroxide in Coloured Bottles:

Protection from Light: Hydrogen peroxide is sensitive to light and can easily decompose under its influence. When exposed to light, it can break down into water and oxygen, which can lead to a decrease in its concentration and effectiveness. Therefore, it is stored in coloured bottles to prevent exposure to light and maintain its potency.

Prevention of Contamination: Hydrogen peroxide can easily react with other substances and become contaminated. For example, it can react with metals, such as copper and iron, and form metal hydroxides, which can reduce its effectiveness. It can also react with organic materials, such as the skin, and cause irritation or burns. Therefore, it is stored in coloured bottles to prevent contamination and protect its purity.

Stability: Hydrogen peroxide is an unstable compound that can easily decompose into water and oxygen gas. When stored in coloured bottles, it is protected from light and other substances that can degrade its stability. This helps to maintain its potency and effectiveness over time.

Regulation: Hydrogen peroxide is a regulated substance that requires special handling and storage. By storing it in coloured bottles, it is easier to identify and track its use, which helps to ensure compliance with regulatory requirements.

In conclusion, hydrogen peroxide is stored in coloured bottles to protect it from light, prevent contamination, maintain stability, and comply with regulatory requirements. These precautions help to ensure that it remains effective and safe for use in various applications.

Answer

Hydrogen peroxide is kept in coloured bottles because it is a high reactive chemical substance. It is stored in bottle to avoid exposure to heat, humidity and alkali metal ions.
