Our episode starts with addressing the question: What IS solubility? (1:19). The episode introduces solubility equilibria with respect to the Solubility-Product Constant, K, expression (1:57) and discussion how its magnitude relates to solubility (3:05). If you have the Ksp you can calculate the molar solubility - in mol/L - as well as the mass solubility in g/L (4:35). Comparing K to Q let’s you determine if a precipitate forms (5:58).
Question: How does a common ion affect the solubility of a salt?
