Text Solution

AI Generated Solution

To prepare looking mirrors, three key components are used: ammonical silver nitrate (AgNO3), red lead, and formaldehyde (HCHO). Each of these components plays a specific role in the process. Here’s a step-by-step explanation of their functions: ### Step 1: Ammonical Silver Nitrate (AgNO3) - **Function**: Ammonical silver nitrate is the primary source of silver ions needed for the deposition of silver on the mirror surface. - **Reaction**: - Ammonical silver nitrate is formed from the reaction of silver nitrate (AgNO3) with sodium hydroxide (NaOH) to produce silver oxide (Ag2O). - The reaction can be represented as: \[ ...
