I loko o ka wai maʻemaʻe, nalowale kekahi hapa liʻiliʻi o nā molekala i hoʻokahi hydrogen mai ka hale H2O, ma ke kaʻina i kapa ʻia ʻo dissociation.Aia i loko o ka wai kekahi helu liʻiliʻi o nā ion hydrogen, H+, a me nā ion hydroxyl koena, OH-.

Aia kahi kaulike ma waena o ka hoʻokumu mau ʻana a me ka dissociation o kahi pākēneka liʻiliʻi o nā mole wai.

Hoʻohui ʻia nā ion hydrogen (OH-) i loko o ka wai me nā molekele wai ʻē aʻe e hana i nā ion hydronium, nā ion H3O+, ka mea maʻamau a kapa ʻia nā ion hydrogen.No ka mea aia kēia mau iona hydroxyl a me hydronium i ke kaulike, ʻaʻole ʻakika a ʻaʻole alkaline ka hopena.

ʻO ka ʻakika he mea ia e hāʻawi i nā ion hydrogen i mea hoʻonā, aʻo ka base a i ʻole ka alkali ka mea nāna e lawe i nā ion hydrogen.

ʻAʻole ʻakika nā mea a pau i loaʻa i ka hydrogen no ka mea aia ka hydrogen i loko o kahi mokuʻāina e hoʻokuʻu maʻalahi, ʻaʻole e like me ka hapa nui o nā pūhui organik e hoʻopaʻa paʻa loa i ka hydrogen i nā ʻātoma kalapona.No laila, kōkua ka pH i ka helu ʻana i ka ikaika o ka waikawa ma ka hōʻike ʻana i ka nui o nā ion hydrogen i hoʻokuʻu ʻia i ka hopena.

He ʻakika ikaika ka ʻakika Hydrochloric no ka mea, ʻo ka paʻa ionic ma waena o ka hydrogen a me nā ions chloride he polar ia i hiki ke hoʻoheheʻe ʻia i loko o ka wai, e hoʻohua ana i nā iona hydrogen he nui a hana i ka hopena i ka waikawa ikaika.ʻO ia ke kumu he haʻahaʻa loa ka pH.ʻO kēia ʻano dissociation i loko o ka wai he mea maikaʻi loa ia ma ke ʻano o ka loaʻa ikaika, ʻo ia ke kumu e maʻalahi ai.

ʻO nā ʻakika nāwaliwali nā pūhui e hāʻawi i ka hydrogen akā ʻaʻole maʻalahi loa, e like me kekahi mau ʻakika organik.Acetic acid, loaʻa i loko o ka vīnega, no ka laʻana, loaʻa ka nui o ka hydrogen akā i loko o kahi hui carboxylic acid, kahi e paʻa ai i loko o nā paʻa covalent a nonpolar paha.

ʻO ka hopena, hoʻokahi wale nō o nā hydrogens hiki ke haʻalele i ka mole, a no laila, ʻaʻole nui ka paʻa i loaʻa ma ka hāʻawi ʻana iā ia.

ʻAe ke kumu a i ʻole ka alkali i nā ion hydrogen, a i ka wā e hoʻohui ʻia ai i ka wai, e hoʻoheheʻe i nā ion hydrogen i hana ʻia e ka dissociation o ka wai i mea e hoʻololi ai ke koena i ke ʻano o ka ʻona hydroxyl ion, e hana i ka hopena alkaline a kumu paha.

ʻO kahi laʻana o kahi kumu maʻamau ʻo ka sodium hydroxide, a i ʻole lye, i hoʻohana ʻia i ka hana ʻana i ke kopa.Ke loaʻa ka ʻakika a me ka alkali i loko o nā ʻano mola like like, e hana koke nā ion hydrogen a me hydroxyl me kekahi i kekahi, e hana ana i ka paʻakai a me ka wai, ma kahi pane i kapa ʻia ʻo neutralization.
