POTASSIUM PHOSPHATE (ACID) Chemical compatibility with O-rings, rubbers, & plastics

Potassium phosphate (acid), also known as monopotassium phosphate (KH2PO4), is a soluble salt commonly used in fertilizers, food additives, and buffering agents. It appears as a white, crystalline powder. In agriculture, it provides essential potassium and phosphorus nutrients to plants, promoting healthy growth and development. In the food industry, it serves as an emulsifier, stabilizer, and pH control agent in various products. Additionally, it is used in laboratory settings as a buffering agent to maintain pH levels in solutions. Monopotassium phosphate is valued for its versatility and effectiveness in a range of applications. Handling this compound requires care, as it can cause skin and eye irritation upon contact.
