constant (Ksp)

The solubility product constant, or Ksp, measures how much of a chemical compound can dissolve in water at equilibrium. It reflects the balance point where the solid compound and its dissolved ions coexist without changing. A higher Ksp means the substance dissolves more readily, creating more ions in solution. Conversely, a lower Ksp indicates it's less soluble and tends to stay as a solid. Ksp helps chemists predict whether a compound will dissolve or form a precipitate under specific conditions, guiding processes like water treatment and mineral formation.
