Sodium hydroxide (NaOH) and oxalic acid (OA) were selected as the alkaline and acid additives, respectively, to investigate whether acid and alkaline additives could promote oxidative desulfurization in the UVH
The pH was determined and controlled using pH meter pH 1100 L provided with a pHenomenal 111 electrode from VWR. 2.2. Materials Oxalic acid (C2H2O4, 98 %), hydrochloric acid (HCl, 37 %), sulfuric acid (Emsure 98 %, H2SO4), hydrogen peroxide (Emprove 30 %, H2O2), sodium carbonate ...
Calculate the mass of oxalic acid dihydrate {eq}C_2H_2O_4 \cdot 2H_2O {/eq} required to react with {eq}30 \ ml {/eq} of {eq}0.20 \ M {/eq} sodium hydroxide solution? Stoichiometry The stoichiometry gives us information abo...
Based on an average experimental water solubility of 220,000 mg/L at 25\u00b0C(1) and a regression derived equation(2), the Koc for undissociated oxalic acid can be estimated to be approximately 5. This Koc value indicates that oxalic acid will have very high mobility in soil(3); there...
