A Ksp (solubility product constant) value greater than 1.0 indicates that the solid phase is relatively soluble. This means that the compound dissociates into its ions more readily in solution, leading to a higher concentration of ions in the solution.
Explanation: The Ksp value is a measure of the solubility of a compound. A higher Ksp value suggests that the compound has a greater tendency to dissolve in water, forming more ions. Therefore, a Ksp value greater than 1.0 typically means that the solid phase is relatively soluble, as opposed to being relatively insoluble.
