A 0.290 g sample of oxalic acid (H_2C_2O_4) was titrated with 0.1533 M NaOH. What volume of dispensed NaOH was necessary to reach the equivalence point? Assume the following reaction: H_2C_2O_4 (aq) + 2Na...
I thought it was just something like H2C2O4•2H2O + NaOH --> NaHC2O4•2H2O + H2O however according to my experiment results, there should be a 2:1 ratio of the NaOH and the acid and I have no idea how to deal with the attached water molecules...Any input is appreciated, ...

The reaction between NaAsO2 and oxalic acid was studied by pH-metric and conductometric measurements, applying the methods of continual variation and pH-metric and conductometric titration. It was found that oxalic acid forms a complex anion of the type [AsOC2O4]-. The relative stability ...

with dilute oxalic acid, the learners find that 25,1 cm3 of the NaOH(aq) neutralises exactly 14,2 cm of the (COOH)2(aq).The balanced equation for the reaction is as follows:2NaOH(aq)+(COOH)_2(aq)→(COO)_2Na_2(aq)+2H_2O(P)7.5.1Calculate the concentration of the oxalic ...
Photocatalytic hydrogen evolution using oxalic acid as electron donor has been investigated over Pt–TiO 2 prepared by photodeposition. The reaction kinetics is consistent with the Langmuir model. The effects of pH, amount of deposited Pt and additives of inorganic anions on the rate of the reaction...
