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 ...
what is the concentration of an oxalic acid solution if it required 16.49 mL 0.1136 M NaOH to reach the equivalence point when 50.00 mL of the H2C2O4 solution was titrated? The titration reaction is given by H2C2O4 (aq) + 2 NaOH (aq) \rightarrow Na2C2O4( ...
Both carboxylic acids were mineralized with high conversions via hypochlorite ion produced in situ, in 0.10M NaCl medium. Highest current efficiency, corresponding to 97%, and highest reaction rate constant for oxalic acid mineralization were obtained for the Ru–Cu/CNT modified electrode, in 0.10M...
