The solubility product constant (Ksp) is used

  1. to determine the concentration of a solute in unsaturated solution.
  2. to calculate the solubility of a solute in a given solvent. ✓
  3. to measure the total mass of a solute that can dissolve in a solvent.
  4. to compare the solubilities of different solutes in the same solvent.
Explanation

Ksp helps calculate how much solute dissolves in a solvent. It shows the maximum amount that can dissolve before precipitation starts.

Ksp works for saturated solutions, not unsaturated ones. It doesn’t measure total mass directly. While you can compare Ksp values, that’s not its main purpose.

Remember: Higher Ksp means more soluble. Lower Ksp means less soluble.
