Calculate [H+],[OH-],[H3PO4],[H2PO4-],[HPO42-],and [PO43-] for a 0.100 M solution of H3PO4.
Use distribution coefficient.Solve the equations.The process can be complex and I'm sorry for not being able to type them all.But I believe that you can solve them all.
Calculate [H+],[OH-],[H3PO4],[H2PO4-],[HPO42-],and [PO43-] f
磷酸氢二钠溶液中,各离子浓度的大小排列顺序是Na+>HPO42->OH->H2PO4->H+>PO43-,
为什么在0.1mol/LNa3PO4溶液中:c[PO43-]+c[HPO42-]+c[H2PO4-]+c[H3PO4]=
h3po4 、h3po3 、h3po2 、h2po4- 、hpo42- 、po43-分别是什么啊.还有“亚”和“次”怎么
HPO42-,H2PO4-,PO43-,CO2-碱性强弱排序
3、H2PO4- 的共轭碱是 ( ) (A) H3PO4 (B) HPO42- (C) H2PO3- (D) PO43-
根据酸碱质子理论,H2PO4-的共轭酸的化学式为( ) 选项:a、HPO42— b、H3PO4 c、PO43—
0.01mol/L的Na2HPO4溶液中存在如下的平衡,HPO42-+H2O=H2PO4+OH- HPO42-=H+ +
H2PO4-、HPO42-、PO43-为什么与H+不能共存?即使它们生成磷酸不也不是弱酸吗?WHY?
物料守恒〔Na+〕=3〔PO43-〕+3〔HPO42-〕+3〔H2PO4-〕+3〔H3PO4〕为什么不是3个钠=后面的离
Na2HPO4溶于水后,水解大于电离.平衡HPO42-=PO43-+H+,使溶液中【HPO42-】,【H+】,【PO43
求酸碱盐溶解性表阴离子:OH- NO3- NO2- SO42- SO32- S2- CO32- PO43- F- ClO
