Wahi a kā lākou acidity, hoʻolaha ʻia nā mea i loko ʻakika, alkaline a i ʻole kūlike ʻole. Ana ʻia ka waikawa ma pH, ka mea kū i ka hydrogen hiki. Loaʻa i kahi mea kūlike kahi pH o 7.
Nā mea ʻona nona ka pH ma lalo o 7, he mea ʻakika. ʻO ka pae acidity kiʻekiʻe loa he pH 0. ʻAikika ke ʻano o ka paʻa o nā ion hydrogen i hoʻopiʻi maikaʻi ʻia ma mua o ka nui o nā ion hydroxyl i uku maikaʻi ʻole ʻia (hydrogen a me oxygen).
ʻAno ʻia nā waikawa e:
- ʻOno ono
- E ʻulaʻula i ka pepa litmus
- Hana i ka effilitiescence me ka calcium carbonate
- Hana lākou me kekahi mau metala e like me ka zinc a me ka hao.
- Hoʻopau lākou kahua
- I ka wai aqueous solution kōkua lākou i ka hele o ke kaʻi uila
- Kūpopo lākou i nā meaolaolaola e like me ka ʻili
- E hoʻopau i nā mea
ʻO ka poʻe i ʻoi aku ka nui o ka pH ma mua o 7, he mau mea alkaline. ʻO ka pae alkalinity kiʻekiʻe loa he pH 14. ʻO ke Alkalinity ʻo ia hoʻi ka nui o nā ion hydroxyl i hoʻoemi ʻia (hydrogen a me oxygen) ʻoi aku ma mua o nā ion hydrogen i hoʻopiʻi maikaʻi ʻia. ʻO nā alkaline, i kapa ʻia hoʻi nā kumu, ʻike ʻia e:
- ʻIno ʻawaʻawa
- Pepa litmus tile
- ʻAʻole kūpono lākou i ka hoʻopā
- Nā mea i hoʻoheheʻe ʻia e nā waikawa piʻi
- I loko o ka wai aqueous solution hoʻolauna pū lākou i ka hele ʻana o ke au uila
- E hoʻonā i nā momona a me ka luaipele
- Hoʻopau lākou i nā waikawa
Nā laʻana o nā mea kūlike ʻole
- Waiu: ka waiū he mea kūlohelohe (PH 6.5). Eia nō naʻe, i ka wā e launa pū ai me nā wai ʻōpū e lilo ia i mea ʻakika, no laila, kūʻē i ka mea i manaʻo pinepine ʻia, ʻaʻole ia e koi ʻia e hoʻopau iā ia ke ʻeha nei ka ʻūʻā.
- Wai holo: ʻo ka wai kahe a i ʻole ka piula wai he mea kūlike ia. Eia nō naʻe, hiki ke hoʻopili ʻia ka wai, ʻo ia hoʻi ka hiki ke hoʻonui ʻia nā ionona hydrogen (hoʻoili maikaʻi ʻia) ma o ka lilo ʻana i acidic.
- ʻO ka wai mineral me gas: ʻO nā minelala a me ke kinoea i ka wai ʻōmole ʻaʻole hoʻololi i ka pH o ka wai ʻōmole nui.
- ʻO ka wai mineral me ka ʻole ka ʻaila
- Kopa wai: ʻo ka ʻili kahi mea waikawa (PH 5.5 e pili ana) ʻoiai nā kīʻaha paʻa paʻa i kahi pH i ʻoi aku ma mua o 8. ʻO nā kopa wai nā huahana synthetic i hoʻohui ʻia ka waikawa e loaʻa ai kahi pH kūlike ʻole. Ua ʻōlelo ʻia ʻo ke kopa Glycerin he "kūleʻa" no ka mea he pH like ia me ka ʻili, akā ʻo ka chemically he mea ʻakika ia, ʻoiai ʻo kona pH ma lalo o 7.
- Kopa holoi wai: ʻOi aku ka haʻahaʻa o ke kopa kūlike ʻole i nā lole ma mua o nā kopa acid.
- Koko: ma waena o 7.3 a me 7.4
- Kuha: ma waena o 6.5 a me 7.4
