How it test the solubility of powder?

To test the solubility of a powder, first, add a known quantity of the powder to a specific volume of solvent (usually water) in a container. Stir the mixture thoroughly and observe whether the powder dissolves completely. If any residue remains after stirring, note the amount that dissolved versus the amount that was originally added. This process can be repeated with varying temperatures or solvents to assess solubility under different conditions.
