Ca3(PO4)2+H2SO4=(就是一个硫酸,不能改化学计量数,下同)Ca3(PO4)2+H3PO4=2CaHPO4+H2SO4=Ca(H2PO4)2+2Na3PO4=H3PO4+Ca(OH)2=2H3PO4+Ca(OH)2=Ca(H2PO4)2+2NaOH=
问题描述:
Ca3(PO4)2+H2SO4=(就是一个硫酸,不能改化学计量数,下同)
Ca3(PO4)2+H3PO4=
2CaHPO4+H2SO4=
Ca(H2PO4)2+2Na3PO4=
H3PO4+Ca(OH)2=
2H3PO4+Ca(OH)2=
Ca(H2PO4)2+2NaOH=
答
Ca3(PO4)2+H2SO4=2CaHPO4 + CaSO4↓
2CaHPO4+H2SO4=???
Ca(H2PO4)2+2Na3PO4=
H3PO4+Ca(OH)2=
2H3PO4+Ca(OH)2=
Ca(H2PO4)2+2NaOH=
崩溃,后面的都不会···%>_
答
Ca3(PO4)2+H2SO4=2CaHPO4 + CaSO4↓
Ca3(PO4)2+H3PO4=3CaHPO4
2CaHPO4+H2SO4=CaSO4↓+ Ca(H2PO4)2
Ca(H2PO4)2+2Na3PO4= CaHPO4+ 3 Na2HPO4
H3PO4+Ca(OH)2= 2CaHPO4+ 2 H2O
2H3PO4+Ca(OH)2=Ca(H2PO4)2 + 2H2O
Ca(H2PO4)2+2NaOH = CaHPO4+Na2HPO4 + 2 H2O
