Answer 1

The best way to separate a solid substance that has dissolved in water is to boil the water away, leaving the substance behind in the beaker. This method will effectively remove the water and retain the dissolved solid as it may precipitate out as the water evaporates.

Using a magnet would only work if the solid is magnetic, and filtering would not separate dissolved substances since they form a solution.

So, the correct response is: Boil the water away, leaving the substance behind in the beaker.
