Question
[11-6d ] Which is the charge-balance equation for the solution that is 0.20 M in Na2HPO4?
1/2 [Na+] = [H3PO4] + [H₂PO4] + [HPO4²] + [PO4³-1
[Na] + [H3O+] = [OH"] + [H₂PO4] + [HPO4²-] + [PO4³-1
[Na] + [H3O+] = [OH¯] + [H₂PO4¯] + 2[HPO4²-] +3[PO4³-]
[Na] + [H3O+] = [H3PO4] + [OH"] + [H₂PO4] + 2[HPO421 +3[PO4³-]
