The technique used to separate a soluble solid from a solution is evaporation.
This method involves heating the solution, causing the solvent (usually water) to evaporate, leaving behind the solid residue.
Here's how it works:
- Heat the solution: Apply heat to the solution in a suitable container, such as a beaker or evaporating dish.
- Evaporation: As the solution heats up, the solvent evaporates, turning into vapor and escaping into the air.
- Solid residue: The dissolved solid remains behind in the container as the solvent evaporates.
Example: Imagine you have salt dissolved in water. By heating the solution, the water evaporates, leaving behind the salt as a solid residue.
Practical insights:
- Evaporation is a common technique used in various industries, including food processing, chemical manufacturing, and pharmaceuticals.
- The type of heating method and the temperature used can vary depending on the specific solution and the desired outcome.
