WebWhat is the correct equilibrium expression (K sp) for the reaction below: Ca 3 (PO 4) 2 (s) ⇌ 3Ca 2+(aq) + 2PO 42-(aq) A K sp = [3Ca 2+ ] [2PO 43-] B K sp = [Ca 2+] 3 [PO 43-] 2 C K sp = [3Ca 2+] + [2PO 43-] D K sp = [3Ca 2+] 3 + [2PO 43-] 2 Solution The correct option is A K sp = [Ca 2+] 3 [PO 43-] 2 K sp = [Ca 2+] 3 [PO 43-] 2 Suggest Corrections WebWe write the dissolution equation and the expression for Ksp. We know the value of Ksp, so we set up a reaction table that expresses [Ca2+] and [OH–] in terms of S, the molar solubility. We then substitute these expressions into the Ksp expression and solve for S. SOLUTION: Ca(OH)2(s) Ca2+(aq) + 2OH–(aq) Ksp = [Ca2+][OH–]2 = 6.5x10–6

Web22 apr. 2024 · Ksp = [Ca^2+]^3 [PO4^-3]^2 Ksp is the produce of the concentrations and raise each to the power indicated by the coefficient. The Ag2CO3 is done the dame way. For the last question note that the first one is the ONLY one with equal ions. CuS ==> Cu^2+ + S^2- Ag2S and Bi2S3 do not produce equation ions. answered by April 23, 2024 Web27 feb. 2014 · Solubility Product Principle • Consider Ca3(PO4)2 dissolved in water • Ca3(PO4)2 = 3Ca2 ... PLAN: The addition of Ca2+, an ion common to both solutions, should lower the solubility of Ca(OH)2.
