Pour the liquid along a rough surface that would catch the solid particles but not the water.

Answer 1

To separate a dissolved substance from water in a lab, the most appropriate method would be to boil the water away, leaving the substance behind in the beaker. This method takes advantage of the fact that the dissolved solid will not evaporate with the water, allowing you to recover it.

The other methods mentioned, such as using a magnet or filtering, are not suitable for separating a dissolved solid, and pouring along a rough surface may not effectively separate the substances.
