**Transcription for Educational Website****5) What is Ksp, and what does it have to do with Beer’s Law?**a) Ksp is a measure of how soluble a slightly soluble salt is. b) Ksp is concentrations of all ions multiplied together. c) We will be using Beer’s Law to measure the concentration of one of the ions, and use the reaction equation to calculate concentrations of other ions, and then to calculate Ksp. d) All of these.**6) What is the Ksp expression for Ca₃(PO₄)₂?**a) [Ca][PO₄] b) [Ca²⁺]²[PO₄³⁻] c) [Ca²⁺]³[PO₄³⁻]² d) [Ca]²[PO₄]³**7) What Ksp value would mean greater solubility?**a) a larger number b) a smaller number c) an equilibrium number d) 1**8) We are determining Ksp of Ca₃(PO₄)₂ experimentally, and have been able to determine the [PO₄³⁻] using a Beer’s Law graph. How can we calculate [Ca²⁺] from it and the reaction equation?**a) Ca₃(PO₄)₂(s) ⇌ 3Ca²⁺(aq) + 2PO₄³⁻(aq). Simplifying the ratio of moles of calcium to moles of phosphate, there are 1.5 moles of calcium for every mole of phosphate in solution. b) Because the volume of solution is the same, concentration of calcium is 1.5 times the concentration of phosphate. c) Finally, we would cube the concentration of calcium and square the concentration of phosphate to get Ksp. d) Whew!
