Whakamahinga
Ko te waikawa oxalicKo te otinga paerewa he otinga waikawa oxalic me te kukū tika e mōhiotia ana, ā, e whakamahia whānuitia ana i roto i ngā mara pēnei i te tātari matū, te whakaputa ahumahi, me te rangahau pūtaiao. Ko ngā tikanga tono matua koia ēnei:
Tātaritanga Matū me te Whakatau
- Te Whakapūtātanga Waikawa-Turanga: Ko te waikawa oxalic he waikawa ngoikore dibasic ka taea te pā ki te tauhohenga whakahāngai me ngā turanga. Ka taea te whakamahi hei otinga waikawa paerewa hei whakatau i te kukū o tētahi otinga kawakore kukū kāore i te mōhiotia. Hei tauira, i te whakapūtātanga o tētahi otinga hauwai konutai ki tētahi otinga paerewa waikawa oxalic, mā te whakamahi i te phenolphthalein hei tohu, ka taea te tatau i te kukū tika o te otinga hauwai konutai i runga i te whanaungatanga stoichiometric me te nui o te otinga paerewa waikawa oxalic i whakamahia i te pito mutunga o te whakapūtātanga.
- Te Whakapūtanga Irahiko: Ko te uara o te huānga waro i roto i te waikawa oxalic he +3, e whakaatu ana i te kaha ki te whakaiti me te kaha ki te tauhohe ki ngā matū whakapūngao kaha i roto i te tauhohenga whakapūngao. I roto i te reo waikawa, ka taea te whakapūngao i te konutai oxalate e te pāhare pākawa waro. Mā te whakamahi i tēnei tauhohenga, ka taea te whakamahi i te otinga paerewa waikawa oxalic hei whakataurite i te kukū tika o te otinga pāhare pākawa waro.
Mana Kounga Ahumahi
- Te Maimoatanga Mata o te Mea Whakarewa: I roto i ngā tukanga maimoatanga mata o ngā mea whakarewa pēnei i te konumohe, ka taea te whakamahi i ngā otinga waikawa oxalic mō te whakairo me te horoi. Mā te whakamahi i te otinga paerewa waikawa oxalic, ka taea te whakahaere tika i te kukū o te otinga kia mau tonu ai te āhua me te pumau o te pānga maimoatanga mata o te mea whakarewa, ā, ka whakapai ake i te kounga o te hua. Hei tauira, mā te whakahaere i te kukū o te otinga paerewa waikawa oxalic i roto i tētahi whānuitanga motuhake, ka taea te whakairo i tētahi hua konumohe kia whiwhi ai i tētahi kakano mata ōrite, ataahua hoki.
- Ahumahi Whakakikorua Hiko: Ka taea te whakamahi i te otinga paerewa waikawa oxalic hei whakatika i te waikawa me te hanganga o te otinga whakakikorua hiko, kia pai ai te kounga me te mahi a te paparanga whakakikorua hiko. Mā te whakahaere tika i te kukū waikawa oxalic ka āwhina ki te whakapai ake i te piri, te kanapa, me te ātete ki te waikura o te paparanga whakakikorua hiko, kia pai ai te tutuki o ngā hua whakakikorua hiko i ngā paerewa kounga.
Te Tākai me te Tukunga
25KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Tukunga: 6 ngā momo taonga morearea, ā, ka taea te tuku mā te moana.
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
