Final answer:
Magnesium hydroxide is a compound used in antacids and laxatives, with a solubility in water of 0.0084 g per liter and a concentration of Mg2+ ions in a saturated solution of 1.31 × 10-4 M. The solubility product constant (Ksp) for magnesium hydroxide can be calculated using this information.
Step-by-step explanation:
Magnesium hydroxide, with the chemical formula Mg(OH)2, is a compound used in antacids and laxatives such as milk of magnesia. Its solubility in water is relatively low, at 0.0084 g per liter, and it forms a saturated solution in which the concentration of Mg2+ is 1.31 × 10-4 M. The solubility product constant (Ksp) for magnesium hydroxide is the product of the concentrations of magnesium ions and hydroxide ions in a saturated solution, and it can be calculated using the given data.
