Understanding the Properties
* Solubility: Sodium chloride (NaCl) is highly soluble in water, while silver chloride (AgCl) is very insoluble.
* Light Sensitivity: Silver chloride is sensitive to light, decomposing into silver and chlorine gas when exposed to strong light.
Separation Method
1. Dissolution: Add water to the mixture of NaCl and AgCl. The NaCl will dissolve, forming a solution, while the AgCl will remain undissolved as a solid.
2. Filtration: Filter the mixture through a filter paper. The undissolved AgCl will be trapped on the filter paper, while the NaCl solution will pass through.
3. Washing: Wash the AgCl on the filter paper with more water to ensure all the NaCl is removed.
4. Drying: Allow the AgCl to dry completely.
5. Recovery of NaCl: You can recover the NaCl from the filtrate by evaporating the water.
Important Notes:
* Light: During the entire process, it's crucial to perform the separation in a dimly lit environment or use a darkroom. This minimizes the decomposition of AgCl due to light exposure.
* Safety: Use appropriate safety equipment, such as gloves and goggles, while handling chemicals.
