🔬 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 | Insoluble Salts |
|---|---|
|
Made by reacting acid with:
Examples: copper sulfate, zinc chloride, sodium nitrate |
Made by precipitation:
Examples: barium sulfate, lead iodide, silver chloride |
