Part F

Part F involves another acid-base neutralization reaction as sulfuric acid dissolves the cupric phosphate to produce a blue cupric sulfate solution and phosphoric acid.

Cu3(PO4)2 + 3H2SO4 -> 3CuSO4 + 2H3PO4

First, the solution was heated on low.

Then it was put through another vacume and wash procedure to get rid of the H2O.

Finally, we added the acidic H2SO4 to the cupric phosphate to create a clear blue cupric sulfate solution.
