Which of the following is a green solvent used for bleaching clothes ?
AHydrogen peroxide
BBenzene
CWater
DLiquified carbon dioxide
Answer:
A. Hydrogen peroxide
Read Explanation:
- Hydrogen Peroxide (H2O2) is widely recognized as a green solvent or an environmentally friendly bleaching agent.
- Mechanism of Action: It functions through the process of oxidation. Upon decomposition, it releases nascent oxygen, which effectively breaks down the chromophores (color-causing molecules) in stains and fabrics, turning them into colorless substances.
- Environmental Impact: Unlike chlorine-based bleaches, Hydrogen Peroxide leaves behind only water and oxygen as byproducts, making it non-toxic and biodegradable.
- Industrial Application: It is frequently referred to as an environmentally benign bleaching agent in the textile and paper pulp industries.
- Safety and Stability: It is safer for fabric fibers compared to harsh chemical bleaches, though its efficacy depends heavily on the concentration and pH level of the solution.
- Chemical Properties: It is a strong oxidizing agent that is stable in acidic conditions but decomposes rapidly in the presence of catalysts or alkaline environments.
