oxalic acid
Oxalic acid is an organic substance with the chemical formula of C It is a metabolite of organisms. It is a binary weak acid, which is widely distributed in plants, animals and fungi and plays different functions in different organisms. It is found that more than 100 kinds of plants are rich in oxalic acid, especially spinach, amaranth, sugar beet, purslane, taro, sweet potato and rhubarb. Because oxalic acid can reduce the bioavailability of mineral elements, it is easy to form calcium oxalate with calcium ions in human body, resulting in kidney stones, oxalic acid is often considered as an antagonist for the absorption and utilization of mineral elements. Its anhydride is carbon trioxide.

Oxalic acid is a naturally occurring organic compound with the chemical formula H2C2O4. It can be found in various plant sources, such as rhubarb, spinach, and certain nuts
Oxalic acid is a colorless, crystalline organic compound with the chemical formula H2C2O4. It is naturally found in various plants, particularly in foods like spinach and rhubarb, and serves as a common component in some household cleaning products. Oxalic acid has versatile applications, most notably as a rust remover and stain cleaner for metal surfaces. In addition to its cleaning properties, it is used as a reducing agent in certain chemical reactions and as a mordant in textile dyeing. However, it should be handled with caution as it can be toxic when ingested in large quantities. Its ability to effectively remove stains and its role in various chemical processes make oxalic acid a valuable compound in both household and industrial settings.

Oxalic acid is an organic substance, chemical form HCO It is a metabolite of living organisms. It is a moderately strong acid. It is widely distributed in plants, animals, and fungi, and performs different functions in different living organisms. Studies have found that more than 100 kinds of plants are rich in oxalic acid, especially spinach, amaranth, beet, purslane, taro, sweet potato and rhubarb and other plants have the highest content. Because oxalic acid can reduce the bioavailability of mineral elements, it is easy to form calcium oxalate with calcium ions in the human body and lead to kidney stones, so oxalic acid is often considered as an antagonist for the absorption and utilization of mineral elements. Its anhydride is carbon sesquioxide.
