- Description:
Product name: Phosphoric Acid
CAS No.:7664-38-2
Molecular formula: H3PO4
EINECS No.: 231-633-2
- Characteristics:
1.Phosphoric Acid is Colorless, transparent and thick liquid, and melting point is 42.3 degrees celsius.
2.It is high boiling acid, non volatile and difficult to decomposition, and easy to soluble in water. As moderately strong acid, its acid is stronger than carbonic acid. When the PH is different, Phosphoric Acid and sodium carbonate react may generate different acid salt.
3.It may irritate human skin to cause phlogosis and destroy the issue of human body; it has got hydroscopic.
