We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. If you mix together two solutions containing barium ions and sulphate ions and the product of the concentrations would exceed the solubility product, you get a precipitate formed. K. sp. Qsp, the ion product, is the products of concentrations of ions in a ratio of products to reactants whereas Ksp, the solubility constant, describes the same ratio at equilibrium conditions. Students will make connections, support their answers with evidence from the text, and summarize. Solubility Product (Ksp) = [products]x/ [reactants]y but..... reactants are in solid form, so Ksp= [products]x Ksp= [A3+]2 [B2–]3 i.e. The Solubility Product Constant • When an excess of a slightly soluble ionic compound is mixed with water, an equilibrium is established between the solid and the ions in the saturated solution and represented by a constant that is temp dependent. The solubility product constant, K sp, like other equilibrium constants is temperature dependent. Solubility is defined as the upper limit of solute that can be dissolved in a given amount of solvent at equilibrium.
