Application Guidance

Phosphoric Acid 30% ACS Grade (ACS) is a strong mineral acid used across pH control, metal pickling, food and beverage processing, and chemical synthesis. Grade and concentration determine the appropriate end-use and materials.

  • Metal pickling, etching, and surface preparation
  • pH adjustment in water and wastewater treatment
  • Regeneration of ion-exchange resins
  • Chemical manufacturing and synthesis
  • Food and beverage processing (food-grade only)

Always add acid to water, never water to acid. Use lined or fluoropolymer piping rated for the concentration; carbon steel is not suitable for dilute acid service.

Storage & Handling

Recommended Storage
塩基、漂白剤および金属から離し、軟鋼ではなくポリエチレンまたはその他の耐酸性容器に密閉して保管すること。Adjudicated
Handling Precautions
Use full PPE including face shield, acid-resistant gloves and apron. Add acid to water slowly with stirring; never reverse. Ventilation required.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities
強塩基(激しい反応)、漂白剤およびその他の次亜塩素酸塩(塩素を発生)およびアンモニア、ほとんどの金属(可燃性の水素を発生)、硫化物、亜硫酸塩およびシアン化物(有毒ガスを発生)。Adjudicated
Shelf Life
Consult Technical Services for product-specific shelf life

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
