Owsleys acids are a type of acid found in nature, specifically in plants such as cranberries and rhubarb. These acids are also known by other names, including oxalic acid, ethanedioic acid, hydrogen oxalate and soluble oxalate. These synonyms are important to know because they refer to the same chemical compound and can often be used interchangeably in scientific literature. Owsleys acids, or any of their synonyms, can be harmful if ingested in high quantities and can lead to kidney damage. Therefore, it's important to understand their properties and potential effects when studying their use in different applications.
