Calculate the molarity of H3Po4 if 358ml of H3PO4 solution is completely titrated by 876ml of 0.0102M Ba(OH)2 solution? 2H3PO4+3Ba(OH)2= Ba3(PO4)2 +6H2O? Chemistry Solutions Dilution Calculations 1 Answer anor277 Jul 5, 2016 Answer: See this old answer, here. Explanation: Titration would not be complete. #H_3PO_4(aq) + Ba(OH)_2(aq) rarr BaHPO_4(aq) + 2H_2O(l)# Is the correct equation, i.e. there is 1:1 molar equivalence between #Ba(OH)_2# and #H_3PO_4(aq)# in water.
