How can NaNO3 recover from a unsaturated solution?
To recover NaNO3 (sodium nitrate) from an unsaturated solution, you can follow a process called crystallization. Here's how you can do it:
1. Start by heating the unsaturated solution containing NaNO3 until the water evaporates. This will result in a concentrated solution.
2. Once the solution becomes concentrated, allow it to cool down slowly. This helps in the formation of larger crystals.
3. As the solution cools, the solubility of NaNO3 decreases. Eventually, the NaNO3 will start to crystallize out of the solution.
4. Once a sufficient amount of crystals have formed, you can separate them from the remaining solution using a filtration process. You can use a filter paper or a fine mesh to collect the crystals while allowing the liquid to pass through.
5. Rinse the collected crystals with a small amount of cold distilled water to remove any impurities that might be stuck to the surface.
6. Finally, you can transfer the crystals onto a watch glass or a filter paper and allow them to dry completely. This can be done by leaving them at room temperature or using a desiccator.
By following this method, you can recover NaNO3 from an unsaturated solution. Remember to handle chemicals with caution and follow appropriate safety measures when performing experiments.
