To separate a solid substance that has dissolved in water, the best approach would be:
**Boil the water away, leaving the substance behind in the beaker.**
This method works if the solid is not volatile, meaning it won't evaporate along with the water. Once the water is boiled away, the solid will remain in the beaker.
Filtering would be applicable if the substance was not dissolved but rather suspended, so it wouldn't be the correct choice for a dissolved solid.
