Ca(OH)2+Ca(H2PO4)2 === CaHPO4↓+2 H2O Ca(OH)2+ 2CaHPO4 === Ca3(PO4)2↓+2H20 现象：开始无明显现象，后产生白色沉淀 若将H3PO4滴加到Ca(OH)2溶液中，发生的反应如下：3 Ca(OH)2+ 2H3PO4 === Ca3(PO4)2↓ + 6 H2O Ca3(PO4)2+H3PO4 === 3 CaHPO4↓ CaH...
Balance the reaction of H3Po4 + Ca(OH)2 = Ca(H2Po4)2 + H2O using this chemical equation balancer!
这是一个分步反应,由于磷酸是分步电离的,根据H3PO4和Ca(OH)2的物质的量决定生成物.如果磷酸过量：2H3PO4+Ca(OH)2=Ca(H2PO4)2+H20 如果还有Ca(OH)2,则：Ca(OH)2+Ca(H2PO4)2=2CaHPO4(沉淀）+H2O 如果Ca(OH)2过量,则：Ca(OH)2+2CaHPO4=Ca3(PO4)2(沉淀）+H2O ...
