How many moles of calcium hydroxide dissolve to generate one mole of dissolved calcium? Given your answer to CTQ 10 and the concentration of calcium in the final solution calculate the mass of calcium hydroxide that can dissolve in 1 L of our 1.0 M solution of sodium hydroxide? (calcium hydroxide MW = 74.09 g/mol) Compare the solubility of calcium hydroxide you just calculated to the solubility of calcium hydroxide in pure water. By what factor did the “common ion”...
Learning Goal: To learn how to calculate the solubility from Kspand vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution: CaF2(s)⇌Ca2+(aq)+2F−(aq) At equilibrium, the ion concentrations remain constant because the rate of dissolution of solid CaF2 equals the rate of the ion crystallization. The equilibrium constant for the dissolution reaction is Ksp=[Ca2+][F−]2 Ksp is called the solubility product and can be determined experimentally by measuring thesolubility, which is the amount...
