Why does silver chloride change colour in the presence of light?
Answer and explanation
Correct answer: Due to photolytic decomposition
Silver chloride is photosensitive. In sunlight, it undergoes photolytic decomposition and forms grey metallic silver, causing the colour change: \(2AgCl \xrightarrow{sunlight} 2Ag + Cl_2\). In a combination reaction, substances join to form a product, whereas here a compound is breaking down.
