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]
Honeybee coated with oxalate crystals. 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.
Oxalic acid binds with calcium to form calcium oxalate crystals which may deposit and cause damage to many areas of the body including the brain, heart, kidneys, and lungs. [7] The most significant effect is accumulation of calcium oxalate crystals in the kidneys which causes kidney damage leading to oliguric or anuric acute kidney failure . [ 7 ]
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 ...
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).
Glyoxylic acid or oxoacetic acid is an organic compound. Together with acetic acid , glycolic acid , and oxalic acid , glyoxylic acid is one of the C 2 carboxylic acids . It is a colourless solid that occurs naturally and is useful industrially.
This chemical is the double ester of phenol with oxalic acid. Upon reaction with hydrogen peroxide , 1,2-dioxetanedione is formed, along with release of the two phenols. [ 2 ] The dioxetanedione then reacts with a dye molecule, decomposing to form carbon dioxide and leaving the dye in an excited state .
Acidic drain cleaners usually contain sulfuric acid at a high concentration which turns a piece of pH paper red and chars it instantly. Apart from grease and hair, an acidic drain cleaner containing sulfuric acid can be also used to dissolve tissue paper inside water pipes. Acidic drain cleaners usually contain sulfuric acid at high ...
