5 C2H2O4 + 2 KMnO4 + 3 H2SO4 →K2SO4 + 2 MNSO4 + 8H2O + 10 CO2; Oxalic acid can also reduce the trivalent iron into bivalent iron. Because of the high solubility of the bivalent iron in the water, we can apply this principle to remove rust on the clothes. ...
These powders were dissolved in 2 M H2SO4 solution with H2O2 as a reducing agent. After dissolving Co and Li components, the solution of oxalic acid was added. Co(II) in leaching solution could be removed in the form of insoluble oxalates. The precipitate formed was crystalline, compact ...
The acid-insoluble lignin contents were determined with 72% H2SO4 according to the TAPPI standard test method(T 222 om-06) at different prehydrolysis periods. The distribution of pseudo-lignin on the surface of bamboo fibers was observed by FE-SEM. The chemical structural changes of bamboo ...
Answer to: What volume of 0.125 M oxalic acid, H_2C_2O_4 is required to react with 35.2 mL of 0.546 M NaOH? H_2C_2O_4 (aq) + 2NaOH(aq) to...
nucleation ability of oxalic acid in the immersion mode has been investigated by controlled expansion cooling runs with airborne, ternary solution droplets composed of, (i), sodium chloride, oxalic acid, and water (NaCl/OA/H2O) and, (ii), sulphuric acid, oxalic acid, and water (H2SO4/OA/...
The Effect of Current Density and Temperature on the Anodic Oxidation of Aluminum in Sulfuric Acid and Oxalic Acid Solutions 99.99% Al specimens were anodized in 10% H2SO4 and 2% H2C2O42H2O solutions at 20, 30, and 40掳C by applying a constant current, ia, in the range 0.5-100mA/cm2...
