How can you determine the solubility of a soluble solid in a given liquid?

The solubility of a soluble solid in a given liquid can be determined by conducting a solubility test, where you add a small amount of the solid to the liquid and observe if it dissolves. If the solid completely dissolves, it is soluble in that liquid. You can also consult solubility tables or literature for information on the solubility of specific solids in different liquids.
