ʻAi keleaweʻike haku mele a me nā hiʻohiʻona?He aha nā ʻano ʻike o ka haku mele keleawe?ʻO nā ʻanuʻu ʻike ʻana i nā ʻanuʻu?He aha nā hiʻohiʻona o ka ʻike ʻana i ka haku mele keleawe?ʻO ka hui keleawe keleawe a mākou e kamaʻilio nei ma ʻaneʻi e pili ana i nā mea i loko o ke keleawe keleawe, ʻoiaʻiʻo, me nā haumia.Pono ke keleawe i loko o ka hoʻohui ʻana i nā ʻāpana keleawe, ʻaʻohe kānalua no kēia.ʻO nā mea hao keleawe ka nui o ke keleawe, ke keleawe a me ka cupronickel.ʻO ke keleawe ʻulaʻula ʻaʻole ia he keleawe keleawe, akā he keleawe maʻemaʻe.ʻElua mau ala nui no ka ʻike ʻana i ka haku mele keleawe.Loaʻa nā ʻano ʻano like ʻole i nā ʻano hana ʻike hoʻohui keleawe keleawe.Nui nā mea hana no ka ʻike ʻana i ka haku mele keleawe.
ʻO ke ʻano o ka hoʻohui ʻana i ke keleawe keleawe?
1. ʻO ke ʻano hoʻolāʻau kemika maʻamau: ʻO nā ʻano hana maʻamau i hoʻohana ʻia i ka nānā ʻana kemika kahiko ke ʻano titration a me ke ʻano gravimetric.
(1) Kaʻina Titration: E like me nā ʻano like ʻole o nā hopena kemika, ua māhele ʻia nā ʻano titration i ka titration acid-base, complexometric titration, redox titration a me precipitation titration.E like me ke ʻano o ke kaʻina hana titration a me ka hopena kemika, ua māhele ʻia nā ʻano titration i ka titration pololei, titration indirect, back titration, a me displacement titration.
(2) Keʻano Gravimetric: ʻO nā ʻano hana gravimetric maʻamau i hoʻohana ʻia no nā ʻāpana keleawe e pili ana i ke ʻano o ka hoʻokaʻawale hohonu, ke ʻano hoʻokaʻawale volatile, ke ʻano hoʻokaʻawale electrolytic a me nā ʻano kaʻawale ʻē aʻe.No ka laʻana, hoʻohana mau ʻia ke ʻano hana gravimetric dehydration silicic acid no ka ʻike ʻana i ke kilika, ke ʻano electrolytic gravimetric e ʻike ai i ke keleawe, a me ka beryllium pyrophosphate gravimetric method e ʻike ai i ka beryllium.
2. ʻO ke ʻano loiloi instrumental: Hiki ke hoʻokaʻawale ʻia ke ʻano loiloi instrumental i ke ʻano loiloi optical, electrochemical analysis method, chromatographic analysis method, etc.Ma waena o lākou, hiki ke hoʻokaʻawale ʻia ka loiloi electrochemical i ke ʻano loiloi hiki, conductometric analysis method, electrolytic analysis method, Coulomb analysis method, polarographic analysis method, etc.
