磷酸（PA）

Phosphoric Acid

化学式：H3PO4

Chemical formula：H3PO4

分子量：98.0

Molecular weight：98.0

执行标准：GB3149-2004(食品级）

Standard executed : GB3149-2004(Food grade）

性状：无色透明的粘稠液体。比重1.70，溶于水并放热。经高温加热便失水生成焦磷酸和偏磷酸，长时间受冷即生成结晶，有腐蚀性，易吸湿，密封保存。

Property：Colorless, transparent and syrupy liquid. It mixes with water in all propertions, producing an amount of heat. It loses water and converts to pyrophosphate and metaphosphoric acid when being high-temperature heated.
