Question:

Copper Sulfate and Sodium Phosphate?

If you have Copper(II) Sulfate + Sodium Phosphatewhat is the molecular, complete net ionic, and net ionic equations?

Answer:

Lancenigo di Villorba (TV), Italy Starting from complex-actions played by anions of phosphoric acid, I remember that hydrogeno-phosphate ion (e.g. HPO4--) may interact with copper ions CuSO4(aq) + Na3PO4(aq) + H2O(aq) <---> <---> CuHPO4(aq) + Na2SO4(aq) + NaOH(aq) Cu++(aq) + PO4---(aq) + H2O(aq) <---> <---> CuHPO4(aq) + OH-(aq) Meanwhile CuHPO4 cannot precipitate, I thought it may form since copper and hydrogeno-phosphate ions carry out a significative value, as follows : Kps = |Cu++| * |HPO4--| remembering the Acid-Base Equilibrium forming the hydrogeno-phosphate ion Ka3 = |PO4---| * |OH-| / |HPO4--| so I rearrange the terms Kps * Ka3 = |Cu++| * |PO4---| * |OH-| The low value of the overwritten relationship confirm the medium stability's level. I hope this helps you.
