Hoʻomaka: Vinegar and Eggshell Experiment
He hoʻokolohua ʻepekema kaulana ka hoʻokolohua ʻana i ka vīnega a me ka ʻili hua no nā haumāna e aʻo e pili ana i nā hoʻololi kemika a me nā waiwai o nā mea like ʻole. Hoʻokomo ka hoʻokolohua i ka waiho ʻana i kahi hua manu i loko o ka vīnega a nānā i kona hopena i ka manawa. ʻO ka nīnau nui e puka mai ana ma kēia hoʻokolohua, "E hoʻoheheʻe anei ka vīnega i kahi pūpū hua?" E ʻimi ana kēia ʻatikala i nā waiwai kemika o ka vīneka a me ka ʻili hua manu a me ke ʻano o ka hana ʻana o kekahi i kekahi, a me ke kaʻina hana o ka hoʻokolohua a me kona hopena.
ʻO ke kinona o ka vīneka a me ka ʻili huamoa
Ma mua o ko mākou komo ʻana i ka hoʻokolohua, pono e hoʻomaopopo i nā waiwai kemika o ka vīneka a me ka ʻili hua. ʻO ka vīnega kahi hopena dilute o ka acetic acid, maʻamau i loaʻa ka 5-8% acetic acid, wai, a me nā mea ʻono ʻē aʻe. ʻO ka ʻakika acetic kahi ʻakika nāwaliwali i hoʻohana mau ʻia no ka kuke ʻana, ka hoʻomaʻemaʻe, a me ka mālama ʻana i ka meaʻai. Ma ka ʻaoʻao ʻē aʻe, ua haku ʻia nā ʻili hua me ka calcium carbonate, ʻo ia ka mineral alkaline. ʻO ka calcium carbonate he pauka keʻokeʻo, ʻaʻala ʻole i hoʻohana ʻia i nā huahana hale he nui, e like me ka toothpaste, chalk, a me nā papa antacid. Loaʻa i nā ʻili hua manu ka liʻiliʻi o ka protein a me nā minela ʻē aʻe, e like me ka magnesium a me ka potassium.
