OXALIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Oxalic acid is an organic compound with the formula C2H2O4. It is a colorless crystalline solid that is highly soluble in water. Oxalic acid is found naturally in many plants, such as rhubarb and spinach, and is used in various industrial and domestic applications. It serves as a cleaning agent, particularly for removing rust and stains, and is also used in the synthesis of other chemicals. In the laboratory, oxalic acid is utilized as a reagent. Handling requires care due to its toxicity, which can cause kidney damage if ingested and irritation upon contact with skin or eyes.
