Ngā patu pepeke
Ko ngā patupatu e pā ana ki ngā matū e whakamahia ana i roto i te ahuwhenua hei ārai me te whakahaere i ngā mate tipu me ngā pepeke riha, me te whakahaere i te tipu o ngā tipu. He whānuitia te whakamahinga i roto i te ahuwhenua, te ngahere me te whakatipu kararehe, te akuaku taiao me te whare, te whakahaere i ngā pepeke me te aukati i te mate urutā, te aukati i te harore me te pūrerehua o ngā hua ahumahi, me ētahi atu.
He maha ngā momo patupatu, ka taea te wehewehe i ēnei ki ngā patupatu, ngā patupatu akari, ngā patupatu kiore, ngā patupatu nemati, ngā patupatu mollusc, ngā patupatu harore, ngā patupatu patu otaota, ngā kaiwhakatikatika tipu tipu, me ētahi atu, e ai ki te whakamahinga; ka taea te wehewehe i ēnei ki ngā kohuke e ai ki te pūtake o ngā rauemi mata. Ngā patupatu pūtake (ngā patupatu kore-waro), ngā patupatu pūtake koiora (ngā mea waro tūturu, ngā moroiti, ngā paturopi, me ētahi atu) me ngā patupatu i hangaia ki te matū, me ētahi atu.
01 houra kautikahei kaihoko here waikawa
Ka puta he matū waikawa i te wā o te tauhohenga rauropi o te hanga patupatu, ā, ka tangohia te waikawa hua mai i te pūnaha tauhohenga mā te tauhohenga whakakore i te houra kautika hei whakatairanga i te tauhohenga pai. Heoi, he āhuatanga e mau tonu ana te houra kautika i te wā e whakamahia ana, e pā ana ki te tere whakarewa.
Ka whakamahia e te hauwai konutai porotaka Binhua tētahi pūnaha porotaka ahurei hei huri i te houra tunutunu mai i ngā maramara ki ngā porotaka, e whakanui ana i te horahanga mata, e ārai ana i te kohikohinga o te hua, ā, e whakarato ana i tētahi taiao tauhohenga kawakore pumau ake.
02 Ka whakaratohia e te houra kautika he taiao tauhohenga kawakore
Kāore te tauhohenga matū o te whakarite patu pepeke e oti i te wā kotahi, engari he maha ngā takahanga waenga, ko ētahi o ēnei me whai āhua kawakore, me tere te whakarewa o te houra kautika totoka kia rite ai te kukū o te houra kautika i roto i te pūnaha.
03Te whakakorenga me te houra kautika
He turanga kaha te houra kautika, ā, ka honoa ngā katote hauwai kua whakakātohia (OH-) i roto i te wairewa wai kime ngā katote hauwai (H+) kua whakaionia e te waikawa hei wai (H2O), ā, ka noho kūpapa te pH o te otinga.
