🔬 Deep Dive: Choosing the Right Method
The method you use depends on whether your salt dissolves in water. Most salts are soluble, but some are insoluble and need a different approach.
Soluble Salts
Made by reacting acid with:
- Metal (if reactive enough)
- Metal oxide
- Metal hydroxide
- Metal carbonate
Examples: copper sulfate, zinc chloride, sodium nitrate
Insoluble Salts
Made by precipitation:
- Mix two soluble salt solutions
- Insoluble salt precipitates out
- Filter to collect the solid
Examples: barium sulfate, lead iodide, silver chloride
