The solubility product for calcium phosphate is K_sp = 1.3 × 10^-26.What is the molar solubility of calcium phosphate?

Question

Quizplus · Accepted Answer

The solubility product expression for calcium phosphate is: K_sp = [Ca2+][PO43-] We need to find the molar solubility of calcium phosphate, which is the concentration of the ions in moles/L when the solid is at equilibrium with its saturated solution. Let's assume that the molar solubility of calcium phosphate is x mol/L. Then, at equilibrium, we have: [Ca2+] = x mol/L [PO43-] = x mol/L Substituting these values into the solubility product expression, we get: K_sp = x * x = x^2 Substituting the value of K_sp, we get: 1.3 × 10^-26 = x^2 Taking the square root of both sides, we get: x = 2.6 × 10^-6 M Therefore, the correct answer is (C).

The Solubility Product for Calcium Phosphate Is Ksp = 1
