QUESTION 30 Which one of the following expressions is the correct representation of Ca2+(aq) concentration involved...
Which one of the following expressions is correct for the representation of Ca2+ (aq) concentration involved in the solubility product (Ksp) of Ca3(PO4)2 in the presence of 0.10 M of Na3PO4: 1. [Ca2+] = (Ksp/0.010)1/2 2. [Ca2+] = (Ksp/0.010)1/3 3. [Ca2+] = (Ksp/0.0010)1/2 4. [Ca2+] = (Ksp/0.0010)1/3
A solution of Na3PO4 is added dropwise to a solution that is 0.0353 M in Ca2+ and 1.43e-08 M in A13+ The Ksp of Ca3(PO4)2 is 2.07e-33. The Ksp of AlPO4 is 9.84e-21. (a) What concentration of PO4 is necessary to begin precipitation? (Neglect volume changes.) [PO3) = (b) Which cation precipitates first? Ca A13+ (c) What is the concentration of PO43- when the second cation begins to precipitate? (PO43-] = M.
Select the correct solubility equilibrium for the slightly soluble salt, calcium phosphate. O CaPO4(s) -- Ca2+(aq) + PO42-(aq) O Ca3(PO4)2(s) — 3Ca2+(aq) + 2P043-(aq) O Ca3PO4(s) — 3Ca+(aq) + PO43-(aq) CaPO4(s) - Ca(aq) + PO4(aq)
For the following equilibrium, Ca, (PO4 )2(s)--3 Ca2 +(aq) + 2 POI-(aq) If Ksp 2.1 x 10-33, what is the molar solubility of Ca, (PO,)? Report your answer with the correct number of significant figures. Sorry, that's incorrect. Try again? 1.15x10 M
