Background: Phosphorus + Copper Sulfate:
I know that the following (unbalanced) reaction proceeds from left to right from this reference, possibly with the formation of elemental copper as well.
This reference (which gets the stochiometry and formula slightly different) agrees.
The net-net is that Phosphorus, Water, and M1SO4 produce (very dilute) H2SO4.
Question One: Would this work with an alkali such as Magnesium or Calcium Sulfates in place of the copper sulfate?
Question Two: It seems unlikely that a weaker acid could make a stronger one, but metathesis is a powerful ally. Can you really mix oxalic acid and magnesium sulfate to produce sulfuric acid and magnesium oxalate? Anyone tried it IRL?
Thanks for your thoughts,

P4 + CuSO4 + H2O -> Cu3P + H3PO4 + H2SO4.
