Ma kemika a me ka ʻepekema waiwai, ʻo nā haumia nā mea kemika i loko o ka nui paʻa o ka wai, ke kinoea, a i ʻole ka paʻa, ʻokoʻa mai ka haku mele ʻana o ka mea a i ʻole ka hui.ʻO ka mea mua, pono e ʻike ʻia kahi kemika maʻemaʻe i ka thermodynamically ma ka liʻiliʻi loa i hoʻokahi pae kemika a hiki ke ʻike ʻia e kāna kiʻi hoʻokahi māhele-phase.ʻO ka lua, ma ka hoʻomaʻamaʻa ʻana, pono e hōʻike ʻia kahi kemika maʻemaʻe he homogeneous (ʻo ia hoʻi, ʻaʻole e hōʻike i ka loli o nā waiwai ma hope o ka hoʻokō ʻana i nā ʻano hana kemika analytical like ʻole).ʻO ka kemika maʻemaʻe maikaʻi loa e hala i nā hoʻāʻo a me nā hoʻāʻo o ka hoʻokaʻawale hou a me ka hoʻomaʻemaʻe.ʻO ke kolu, a ma ʻaneʻi ke nānā aku nei mākou i ka wehewehe kemika maʻamau, ʻaʻole pono e loaʻa kekahi ʻano o nā ʻano mea kemika ʻē aʻe.ʻO ka ʻoiaʻiʻo, ʻaʻohe 100% o nā pūhui kemika maʻemaʻe, no ka mea, aia mau kekahi mau minuke.ʻOiaʻiʻo, i ka emi ʻana o nā palena ʻike i ka kemika analytical, mahuahua ka nui o nā haumia i ʻike ʻia.

Hoʻopili maoli ʻia a hoʻohui ʻia paha nā mea haumia i ka wā synthesis o kahi huahana kemika a i ʻole nā ​​​​huahana kūʻai.I ka wā o ka hana ʻana, hiki ke hoʻohui ʻia nā mea haumia i loko o ka waiwai.

ʻO nā pae o ka haumia i loko o kahi mea i wehewehe ʻia ma nā huaʻōlelo pili.Ua hoʻokumu ʻia nā kūlana e nā hui like ʻole e hoʻāʻo nei e wehewehe i nā pae i ʻae ʻia o nā mea haumia like ʻole i loko o kahi huahana i hana ʻia.ʻO ka ʻōlelo koʻikoʻi, a laila hiki ke ʻōlelo ʻia ke kiʻekiʻe o ka maʻemaʻe o kahi mea ma ke ʻano he ʻoi aku ka maʻemaʻe a emi ʻole ma mua o kekahi mau mea ʻē aʻe.
