  2. Sodium oxalate - Wikipedia

    en.wikipedia.org/wiki/Sodium_oxalate

    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.

  3. Manganese oxalate - Wikipedia

    en.wikipedia.org/wiki/Manganese_oxalate

    Manganese oxalate is a chemical compound, a salt of manganese and oxalic acid with the chemical formula MnC 2 O 4. [2] [3] The compound creates light pink crystals, does not dissolve in water, and forms crystalline hydrates. [4] It occurs naturally as the mineral Lindbergite. [5]

  4. Oxalic acid - Wikipedia

    en.wikipedia.org/wiki/Oxalic_acid

    Oxalic acid is sometimes used in the aluminum anodizing process, with or without sulfuric acid. [57] Compared to sulfuric-acid anodizing, the coatings obtained are thinner and exhibit lower surface roughness. Oxalic acid is also widely used as a wood bleach, most often in its crystalline form to be mixed with water to its proper dilution for use.

  9. Calcium oxalate - Wikipedia

    en.wikipedia.org/wiki/Calcium_oxalate

    Calcium oxalate crystals are commonly found in lichens, where they occur in two mineral forms: weddellite (CaC 2 O 4 ·(2+x)H 2 O) and whewellite (CaC 2 O 4 ·H 2 O). These crystals can form both on the surface of the lichen as a powdery coating called pruina and within the internal structures of the lichen thallus. The type and distribution of ...
