Phosphoric Acid
Physicochemical properties:
1. Colorless transparent liquid, No irritant smell.
2.Melting point 42℃; boiling point 261℃.
3.Miscible with water in any ratio.
Storge:
1. Store in a cool, ventilated warehouse.
2. Keep away from fire and heat sources.
3. The package is sealed.
4. It should be stored separately from easily (combustible) combustibles, alkalis, and active metal powders, and avoid mixed storage.
5. The storage area should be equipped with suitable materials to contain the leakage.
