Whakamahia:
Te whakamahi ahuwhenua: nga rauemi mata o te tongi phosphate me nga matūkai whangai
Ahumahi whakamahi: matū raw rauemi
1. Tiakina te whakarewa mai i te waikura
2.Mixed ki te waikawa nitric rite matū oro agentto whakapai ake i te mutu mata o te whakarewa
3.Material o te phosphatide e whakamahia ana mo te hua horoi me te ngarara
4.Ko te hanga o te ūkuikui kei roto nga rauemi muramura.
Ka whakamahia nga taapiri kai: te kakara waikawa, te rewena Nutri-ents, penei i te coca-cola.
Te whakamahi rongoa: ki te whakaputa rongoa kei roto te phos-phorus, penei i te Na 2 Glycerophosphat
Ko te waikawa Phosphoric orthophosphoric ranei, te tauira matū H3PO4, te taumaha ngota 97.9724, he waikawa pararopi noa, he waikawa kaha reo. Ka whiwhihia ma te whakakore i te phosphorus tetroxide ki te wai wera. Ka whiwhihia te waikawa Orthophosphoric i te hokohoko ma te rongoa i te apatite me te waikawa pungatara. Ko te waikawa Phosphoric he ngawari ki te whakaheke i te hau. Ka ngaro te wai o te wera ki te waikawa pyrophosphoric, ka ngaro te wai ki te metaphosphate. Ko te waikawa Phosphoric te nuinga e whakamahia ana i roto i te rongoa, te kai, te tongi me etahi atu ahumahi, ka taea hoki te whakamahi hei reagent matū.
Hanganga rawa
Ko te Orthophosphate he waikawa phosphoric i tito mai i te tetrahedron phospho-oxygen kotahi. I roto i te ngota ngota waikawa ūkuikui, he sp3 ranu te ngota P, e toru nga orbital ranu e hanga ana e toru nga here sigma ki te ngota hāora, me tetahi atu herenga P - O he mea hanga mai i te ūkuikui ki te hāora me nga here d-pπ e rua mai i hāora ki te ūkuikui. Ka hangaia he here sigma e te rurukutanga o nga irahiko takirua takitahi mai i te ngota ūkuikui ki te orbital watea o te ngota hāora. Ka hangaia te here d←p ma te inaki i te py me te pz o nga ngota hāora ki nga orbital watea o te dxz me te dyz o nga ngota ūkuikui. I te mea ko te kaha 3d o nga ngota ūkuikui he teitei ake i te 2p o nga ngota hāora, karekau i tino pai nga orbital rapoi, no reira ko nga here PO he hononga takitoru i runga i te tau, engari he takawaenga i waenga i nga hononga kotahi me te takirua i runga i te kaha here. me te roa here. Ko te noho mai o nga here hauwai i roto i te H3PO4 parakore me ona hydrates tioata pea te ahua o te pokey o te wairewa waikawa phosphoric.
Mara tono
