Oxalic Acid is one of the oldest known organic acids. It was first identified as a constituent of the oxalic family plants. It is the first member of the dicarboxylic acid series. Dicarboxylic acids are acids that have two carboxyl groups in their molecules and as such are dibasic. Oxalic acid and its salts are widely distributed in nature. Oxalic acid is found as the free acid in beet leaves and as the monopotassium salt in wood sorrel, rhubarb and spinach. The cooking process destroys oxalic acids in foods. Ethanedioic acid is also known as oxalic acid. It is a stable dicarboxylic acid by composition and structure. In plants and vegetables, oxalic acid is a naturally occurring organic acid.
In sea water, boric acid and its salts are found. It is also present in trees, with almost all fruits included. It is also present as a part of borax, boracite, ulexite (boronatrocalcite) and colemanite, several naturally occurring minerals. Two different formulations of the same compound are Borax and Boric Acid. Borax is a mineral that is extracted straight from the earth (a form of the Boron element) and used in cleaning materials. In a variety of chemical products, the processed, purified and processed source of boric acid is used.
Oxalic Acid Uses
Oxalic has many industrial uses that display its unique properties. The major uses of oxalic acid are for metal chelation , bleaching, and for buffering pH. Oxalic acid is used for the printing and dyeing of calico, bleaching of straw hats and leather, and wood washing. It may also be used to remove stains with ink, it is also an effective concrete & metal rust stain remover. Oxalic Acid is used to remove dark stains, water marks & to refresh the colour of the trees, particularly oak.
Oxalic acid is primarily used for the production of antibiotics such as borneol and antibiotics and solvent for the extraction of rare metals, diminishing agents and dyes, tanning agents, etc. In addition, oxalic acid can also be used with diethyl oxalate, sodium oxalate and calcium oxalate with the highest yield for the synthesis of different forms of oxalate ester, oxalate and oxamide.
Oxalic acid can primarily be used as a reducing agent and a bleaching agent, a mordant for the dyeing and printing industries, often used in the refining of rare metals, the synthesis of different amides of oxalate ester, oxalate and grass, etc.
Application of Boric Acid
Boric acid is a transparent, crystalline powder, soft and soapy to the touch. Boric acid is very soluble in cold water, although it’s relatively soluble in hot water. Once boric acid is hot, it decomposes at 375 K to form metaboric acid, tetraboric acid at 435 K, and boron trioxide is converted into red heat.
Boric acid (H3BO3), a very acidic acid as it dissociates with large doses according to the equilibrium and has been shown by Biswanger, its activity is only understood from unintentional toxicity. Several boric acids derived from boron trioxide with varying water concentrations are known. Orthoboric acid or simply boric acid is the most significant of these.
Because of the enormous use of borax in the manufacturing of porcelain, the market for boric acid has risen. As imported from these sources, the crystals of boric acid contain salts of ammonia and other impurities.
