  • ʻO ka pH kahi ana o ka hana hydrogen ion i kahi hopena. ʻO ka wai maʻemaʻe i loaʻa ke kaulike kaulike o nā ion hydrogen maikaʻi (H +) a me nā ion hydroxide ʻino (OH -) he pH kūlike ʻole.

    ● ʻO nā hāʻina me kahi kiʻekiʻe o nā hydrogen ions (H +) ma mua o ka wai maʻemaʻe he acidic a loaʻa kahi pH ma lalo o 7.

    ● ʻO nā hopena me kahi kiʻekiʻe o nā ion hydroxide (OH -) ma mua o ka wai he kumu (alkaline) a loaʻa ka pH ma mua o 7.

    ʻO ke ana ʻana pH kahi kī nui i nā hoʻokolohua wai a me nā kaʻina hana hoʻomaʻemaʻe.

    ● Hiki ke hoʻololi i ka pae pH o ka wai e hoʻololi i ka lawena o nā kemika i loko o ka wai.

    ● Hoʻololi ka pH i ka maikaʻi o ka huahana a me ka palekana o nā mea kūʻai. Hiki i nā loli i ka pH ke hoʻololi i ka ʻono, ke kala, ka papa-ola, ka paʻa o ka huahana a me ka acidity.

    ● Ka lawa ʻole o ka pH o ka wai piula i hiki ke hoʻowalewale i ka ʻōnaehana hāʻawi a hiki ke ʻae i nā metala kaumaha e kū i waho.

    ● ʻO ka mālama ʻana i nā wahi o ka wai ʻoihana pH e kōkua i ka pale ʻana i ka pala a me ka hōʻino ʻana i nā lakohana.

    1. Hoʻonā ikaika i ka electrode i kahi wai holoi.

    2. E hoʻoluliluli i ka uila me ka hana wikiwiki e hemo ai i nā koena o ka hopena.

    3. E hoʻoulu ikaika i ka electrode i ka buffer a i ʻole ka laʻana a ʻae i ka heluhelu ʻana e paʻa.

    4. E lawe i ka heluhelu a hoʻopaʻa i ka waiwai i ʻike ʻia o ka pae hoʻohālikelike.
