  2. Titration curve - Wikipedia

    en.wikipedia.org/wiki/Titration_curve

    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 ...

  3. Oxalic acid - Wikipedia

    en.wikipedia.org/wiki/Oxalic_acid

    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 ...

  4. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular and the pH shifts less with small additions of titrant near the equivalence point. For example, the titration curve for the titration between oxalic acid (a weak acid) and sodium hydroxide (a strong base) is

  5. Ammonium oxalate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_oxalate

    It is an ammonium salt of oxalic acid. It consists of ammonium cations ([NH 4] +) and oxalate anions (C 2 O 2− 4). The structure of ammonium oxalate is ([NH 4] +) 2 [C 2 O 4] 2−. Ammonium oxalate sometimes comes as a monohydrate ([NH 4] 2 C 2 O 4 ·H 2 O). It is a colorless or white salt under standard conditions and is odorless and non ...

  6. Oxalate - Wikipedia

    en.wikipedia.org/wiki/Oxalate

    Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4.This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4).

  7. Oxalate degrading enzyme - Wikipedia

    en.wikipedia.org/wiki/Oxalate_degrading_enzyme

    Oxalate oxidase (Enzyme Commission number EC 1.2.3.4 [2] )occurs mainly in plants. It can degrade oxalic acid into carbon dioxide and hydrogen peroxide. [3]Oxalate decarboxylase (OXDC,EC 4.1.1.2) is a kind of oxalate degrading enzyme containing Mn 2+, [4] found mainly in fungi or some bacteria.

  9. Equivalent weight - Wikipedia

    en.wikipedia.org/wiki/Equivalent_weight

    It is necessary to calculate the mass of a solid acid which will react with about 20 cm 3 of this solution (for a titration using a 25 cm 3 burette): suitable solid acids include oxalic acid dihydrate, potassium hydrogen phthalate and potassium hydrogen iodate. The equivalent weights of the three acids 63.04 g, 204.23 g and 389.92 g ...
