Question:

A solution is made by adding 2x10^-4 moles of oxalic acid (which we will represent as H₂Ox), 5x10 ^-4 moles NazHPO4, and 5x10 4moles CuCl₂ to 1.0 L of pure water.

(a) Prepare a log C - pH diagram showing the speciation of TOTOx, TOTPO₄, and TOTCu in the system.

(b) H₃PO₄ is added to the original solution until the pH is 6.5. Designating the dose of H3PO4 added (in mol/L) as x, write out the TOTH equation for the solution, using the species that are expected to be dominant in the new solution as the components.
