How should silver nitrate solutions be stored if kept for a long time?

• A. In a clear bottle
• B. In a well-stoppered dark-colored bottle or dark place
• C. In the refrigerator
• D. At room temperature in light

Answer: (B)

Silver nitrate solutions are sensitive to light and can decompose when exposed to it, leading to changes in their chemical composition and effectiveness. Storing silver nitrate in a well-stoppered dark-colored bottle helps protect the solution from light exposure, which is critical for maintaining its stability and efficacy over extended periods. Additionally, using a dark place for storage further minimizes the risk of photodegradation. This practice ensures that the silver nitrate retains its intended concentration and properties, which is crucial for its applications in latent print development. It's important to note that while refrigeration is a common method for preserving many chemical solutions, it is not specifically required for silver nitrate, and storing it at room temperature away from light is preferable.
