Oxalic acid is used by some beekeepers as a miticide against the parasitic varroa mite. [52] Dilute solutions (0.05–0.15 M) of oxalic acid can be used to remove iron from clays such as kaolinite to produce light-colored ceramics. [53] Oxalic acid can be used to clean minerals like many other acids. Two such examples are quartz crystals and ...
[citation needed] Leaves of the tea plant (Camellia sinensis) contain among the greatest measured concentrations of oxalic acid relative to other plants. However, the drink derived by infusion in hot water typically contains only low to moderate amounts of oxalic acid due to the small mass of leaves used for brewing. [citation needed]
It is the sodium salt of oxalic acid. It contains sodium cations Na + and oxalate anions C 2 O 2− 4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. [2] Sodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO 4) solutions.
A typical titration curve of a diprotic acid, oxalic acid, titrated with a strong base, sodium hydroxide.Both equivalence points are visible. Titrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the ...
Oxalic acid, also called ethanedioic acid, belongs to the carboxylic acid family. Oxalic acid is used widely as an acid rinse in the laundry industry due to its ability to remove rust and ink stains. Oxalic acid converts insoluble iron compounds into a soluble complex ion. It is because of this property that oxalic acid is one of the primary ...
Cerium(III) oxalate (cerous oxalate) is the inorganic cerium salt of oxalic acid. It is a white crystalline solid with the chemical formula of Ce 2 (C 2 O 4 ) 3 . It could be obtained by the reaction of oxalic acid with cerium(III) chloride .
For this reason, organic acids are used at high temperatures or when long contact times between acid and pipe are needed. [citation needed] The conjugate bases of organic acids such as citrate and lactate are often used in biologically compatible buffer solutions. Citric and oxalic acids are used as rust removal.
Dimethyl oxalate (and the related diethyl ester) is used in diverse condensation reactions. [7] For example, diethyl oxalate condenses with cyclohexanone to give the diketo-ester, a precursor to pimelic acid. [8] With diamines, the diesters of oxalic acid condense to give cyclic diamides.
