The value of K sp for barium carbonate is 2 .6 × 1 0 - 9 . ;
The Ksp of barium carbonate can be calculated by converting its solubility from g/L to mol/L, which is approximately 0.00005068 mol/L. Since one mole of BaCO₃ produces one mole of Ba²⁺ and one mole of CO₃²⁻, the Ksp is calculated as approximately 2.6 × 10⁻⁹.
