(a) Interpretation: Whether solubility of BaCO 3 increases, decreases or remains unchanged on addition of HNO 3 should be identified. Concept introduction: The solubility of compounds depends on pH of solution. Also, the solubility of compound such as oxide and strong base is dependent on pH. The pH of ionic compound is inversely proportional to solubility. The solubility of salt that has basic anion will increase. If strong acid is added to solution, the concentration of anion decrease which decreases the magnitude of ion form. In accordance to Le Chatelier’s principle, acidic pH increases the solubility of salt that has anion that is conjugate base of weak acid. Also, pH has no effect on the solubility of salt that has anion of conjugate base of strong acid.

Because barium sulfate is opaque to X-rays, it is suspended in water and taken internally to make the gastrointestinal tract visible in an X-ray photograph. Although barium ion is quite toxic, barium sulfate’s Ksp of 1.1 x 10–10 gives it such low solubility that it can be safely consumed.
(a) What is the molar solubility of BaSO4?
(b) What is its solubility in grams per 100 g of water?
