Silver nitrate is usually kept in coloured bottles because it is : — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Silver nitrate (AgNO3) is a light-sensitive chemical compound. Step 2: Upon exposure to light (especially sunlight), it undergoes photodecomposition to yield metallic silver, nitrogen dioxide, and oxygen: 2AgNO3 ---> 2Ag + 2NO2 + O2. Step 3: Storing silver nitrate in dark or amber-colored bottles prevents light transmission and stops this decomposition. Thus, option (b) is correct.
