22.214.171.124 Trends in properties
The trend in reducing ability of the halide ions, including the reactions of solid sodium halides with concentrated sulfuric acid. The use of acidified silver nitrate solution to identify and distinguish between halide ions. The trend in solubility of the silver halides in ammonia.
Students should be able to explain why:
• silver nitrate solution is used to identify halide ions
• the silver nitrate solution is acidified
• ammonia solution is added.
