(a) pure water The K sp for strontium chromate is 3.6E-5 and the K sp for barium chromate is 1.2E-10. A solution whose concentration is at the solubility limit for a given temperature is said to be saturated acids. Old substances are converted into new substances, which have unique physical and chemical properties of their own. Solubility Equilibrium defines the dynamic equilibria between a precipitate and its dissolved ions when the rate of dissolution equals the rate of crystallization and the resulting solution is a saturated solution, that contains the maximum concentration of dissolved ions that coexist with the undissolved solute (precipitate). Since the Ksp for barium chromate is smaller, we know that \(\ce{BaCrO4}\) will form a precipitate first as \(\ce{[CrO4^2- ]}\) increases so that Qsp for \(\ce{BaCrO4}\) also increases from zero to Ksp of \(\ce{BaCrO4}\), at which point, \(\ce{BaCrO4}\) precipitates. For ionic compounds with limited solubility in water, an equilibrium constant, K sp, can be defined from the ion concentration in water from the equation:. \(\ce{[Ba^2+]\,} \textrm{3.6\times 10^{-4} = 1.2\times 10^{-10}}\).
