PHOSPHORIC ACID 3 MOLAR TO 158°F Chemical compatibility with O-rings, rubbers, & plastics

Phosphoric acid, 3 molar concentration, heated to 158°F, is used in various industrial and laboratory applications requiring controlled acidic conditions at elevated temperatures. It maintains the properties of phosphoric acid, including its use in food processing, fertilizers, and metal treatments. At this concentration and temperature, it can cause more severe skin and eye irritation, necessitating strict handling protocols. Protective equipment, such as gloves and safety goggles, is essential to prevent exposure. Proper ventilation and temperature control are crucial to avoid the release of fumes. It should be stored in corrosion-resistant containers, away from incompatible materials like strong bases and reactive metals. In case of spills, neutralization and prompt cleanup are necessary to mitigate environmental impact. The elevated temperature enhances its reactivity, making it effective for specific applications in industrial and laboratory settings.
