He aha te Trisodium phosphate?

Ko te phosphate trisodium, e mōhiotia ana ko te 'sodium orthophosphate'. Ko te tātai matū ko Na3PO4 · 12H2O. He tioata āhua ngira, he paura tioata rānei, he kore tae, he ma, me te ira rewa o te 73.4 °C mō te dodecahydrate. Ka rewa ki te wai, ka kitea te kaha o te kawakore i roto i te wai nā te kaha o te waikura o ngā katote phosphate (PO43-); Kāore e rewa ki te etanoru me te waro disulfide. Ka ngawari ki te memeha me te huarere i te hau maroke, ka puta he phosphate dihydrogen konutai me te paikāponate konutai. Tata tonu te memeha ki te phosphate hauwai disodium me te hauwai konutai i roto i te wai. Ko te phosphate trisodium tētahi o ngā raupapa hua nui i roto i te umanga phosphate, e whakamahia whānuitia ana i roto i te umanga matū hou, te ahuwhenua me te whakatipu kararehe, te hinu, te hanga pepa, ngā hopi horoi, ngā uku me ētahi atu mara nā ōna āhuatanga motuhake.
