也谈P4O10与H2O反应生成HPO3或H3PO4的反应条件河南省郑州市中牟一高(451450)梁国顺在96.3《化学教学》上有文P4O10与水反应生成HPO.或H.PO.的条件不是温度,而是水的用量.对此见解,愚不能与之苟同.为了澄清事实...梁国顺河南省郑州市中牟一高化学教学...
故答案为:; NaOH+H3PO2=Na H2PO2+H2O;H3PO2、H3PO3、H3PO4中磷元素的化合价依次为+1,+3和+5价,中心磷原子的正电荷依次升高,导致P-O-H中O的电子更易向P偏移,因而H3PO2、H3PO3、H3PO4越易电离出氢离子,酸性越来越强;(3)三溴化硼分子中硼原子的价层电子对数为3+323+32=3,B原子按sp2方式杂化,没有...
