1. A solution is made by adding 2104 moles of oxalic acid (which we will represent as H2Ox),5104 moles Na2HPO4, and 5104 moles CuCl2 to 1.0L of pure water. (a) Prepare a logCpH 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
