Oxalic acid is a naturally occurring dicarboxylic acid found in plants such as spinach and rhubarb. It is widely used in cleaning agents, metal polishing, bleaching, and as a chemical intermediate in various industrial processes. In high amounts, oxalic acid can be toxic due to its ability to form insoluble calcium oxalate crystals.
