磷酸的化學(xué)性質(zhì),質(zhì)量標(biāo)準(zhǔn)及用途

  
性狀

無(wú)色透明粘稠狀液體或斜方晶體,無(wú)臭、味很酸。85%磷酸是無(wú)色透明或略帶淺色,稠狀液體。熔點(diǎn)42.35℃,比重1.70,高沸點(diǎn)酸,可與水以任意比互溶,沸點(diǎn)213℃時(shí)(失去1/2水),則生成焦磷酸。加熱至300℃時(shí)變成偏磷酸。相對(duì)密度181.834。易溶于水,溶于乙醇。是一種常見(jiàn)的無(wú)機(jī)酸,是中強(qiáng)酸。其酸性較硫酸、鹽酸和硝酸等強(qiáng)酸弱,但較醋酸、硼酸、碳酸等弱酸強(qiáng)
