pH-metryThe 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 ...
Oxalic acid is a diprotic acid. Calculate the percent of oxalic acid (H_2C_2O_4) in a solid given that a 0.7984 gram sample of that solid required 37.98 mL of 0.2283 M NaOH for neutralization. A sample of ox...

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...
As the dissolution requires a pH controlled in the region 2.5–3.0 for maximum reaction rate, it is essential to create a hydroxide-oxalate mixture for use in the leaching process. The characteristics of NaOH-, KOH- and NH4OH-oxalic acid mixtures were also determined in this study. Due to ...

However, it is possible that due to the deposition of metal oxalates on the cathode particles they are shielded from further acid attack [23]. The overall leaching reaction equation is shown below [23]:(5)4H2C2O4+2Li(NiMnCo)13O2=Li2C2O4+2(NiMnCo)1/3C2O4+4H2O+2CO2 Download: ...
