- Oxalic is toxic, but it produces no fumes, no smell, you can use it even inside. Unless you eat few spoonfuls or drink a liter of oxalic solution (very untasty), you are fine. Its very weak acid so no big issue with etching the skin, but because of its toxicity it's better ...
In this study, the effects of a weak oxalic acid (OA) water solution (0.5%) and a mixture of oxalic acid (0.5%) and thymol (0.12%) (OA/TH) on Varroa mites and honey bees were investigated by trickling method. Prior to the experiments, queens in colonies were caged for 21 days to...

Indeed, more generally, carboxylate-substrate bonding is widely used to tether a range of molecules to surfaces (e.g. [1]). The presence of the formate species HCOO, the deprotonated form of the simplest carboxylic acid, formic acid (HCOOH, FoA – see Fig. 1), on Cu(110) was first ...

Rare earth elements (REEs) are considered to be one of the most important metal raw materials, and coal seams are one of the potential sources of REEs. As a low-molecular-weight organic acid, oxalic acid has a strong ability to migrate and dissolve miner
The recovery of valuable metals from spent lithium-ion batteries is beneficial to protect the environment and avoid resource depletion. Based on the synergistic effect of the reducing ability of oxalic acid and the acidic strength of sulfuric acid, this
5. A method of manufacturing a negative ion generating medium characterized by subjecting a mother material made of aluminum or aluminum alloy and covered at the surface with an anodized layer to the electrolytic process in a phosphoric acid bath to modify the shape of the anodized layer and el...
Total and molybdate reactive P extracted with weak (I mM), acid (9.35 mM, pH 2.3). and strong (50 mM) oxalate correlated well with Na2SO4 + NaF, Olsen P, and Bray I extractable P (0.96 > r > 0.77). Total and molybdate reactive P fractions determined by different oxalate methods ...
