Question

11. Why do we store silver chloride in dark coloured bottle. Explain the reason and write the chemical equation of the reaction involved.​

Answer 1

Answer:

Compounds Like Silver chloride are light sensitive and they may react to light very fast and lose its properties. That's why they are to be stored in dark bottles to prevent the entry of light. AgCl is converted to molecular Ag aoms by the effect of photons of light.

Explanation:

Answer 2

Silver chloride is a light-sensitive chemical compound and it easily undergoes a photolytic decomposition reaction. It reacts with the light rapidly and loses its characteristic by forming chlorine gas and silver. Hence silver chloride is stored in dark coloured bottles.

Explanation

Silver chloride decomposes into silver and chlorine gas when exposed to sunlight. Dark-coloured bottles interrupt the path of light such that light cannot reach silver chloride in the bottles and its decomposition is prevented. It is known that silver chloride decomposes to silver and chlorine in the presence of light. They act as a filter and this prevents the reactions Hence Silver chloride is stored in dark-coloured bottles.

Reaction

2AgCl→2Ag + Cl2
