Kupu Whakataki
Ko te waikawa Phosphoric he pūhui pararopi me te tātai matū H3PO4. Ko te ahua he karaihe kore tae, he maramara marama, he ngawari te wairewa ki te wai. He waikawa te waikawa Phosphoric ka taea te tauhohe ki nga konganuku ki te whakaputa hau hauwai, me te tauhohe ki nga waipiro hei hanga i nga hauwai phosphate.
Ka whakamahia nuitia te waikawa Phosphoric i roto i nga momo ahumahi, tae atu ki te mea hei rauemi mata mo te hanga maniua, hei horoi, me nga taapiri kai. Ka whakamahia ano ki te hanga i nga tote phosphate, nga rongoa, me nga mahi matū. I roto i te matū koiora, ko te waikawa ūkuikui he wāhanga nui o ngā pūtau, e whai wāhi ana ki te pākia pūngao me te whakahiato DNA, me ētahi atu tukanga koiora.
Ko te hanga o te waikawa phosphoric i te nuinga o te waa ka uru ki nga tukanga maku me te maroke. Ko te tukanga maku ko te whakamahana i te toka phosphate (pēnei i te apatite me te phosphorite) ki te waikawa pungatara ki te whakaputa waikawa phosphoric, i te tukanga maroke ko te calcination o te toka phosphate ka whai i te tangohanga maku me te tauhohenga ki te waikawa sulfuric.
I roto i te hanga ahumahi me te whakamahi, ko te waikawa phosphoric he raru mo te haumaru. Ko te waikawa phosphoric tino kaha he kino te waikura, ka whakapataritari me te kino ki te kiri me te manawa. No reira, me whai tikanga tiaki kia kore e pa ki te kiri me te ngohanga o ona kohu i te wa e whakahaere ana i te waikawa phosphoric. I tua atu, ko te waikawa phosphoric ano he raru mo te taiao, na te nui o te rerenga ka pa ki te wai me te poke o te oneone. No reira, he mea nui te whakahaere me nga tikanga tuku para para i te wa e whakaputa ana me te whakamahi.
