A sample of cola drink (exactly 100.0 mL) was titrated with 0.1025 N NaOH. If the first equivalence point occurred after 13.11 mL of base were added, and the second equivalence point occurred after 28.55 mL of base, calculate the concentration of H3PO4 and H2PO4- in the cola sample (Hint: Where should the second equivalent point have occurred if only H3PO4 were present? Since the observed endpoint occurs beyond the point where we expect it to occur for a sample...
