Paʻakai kalepona, paʻakai hydrogencarbonate - loa hana hoihoi

Kemika - hoihoi 'epekema e wehewehe loa o ka hana ma kai a puni mākou keʻano o ka hanaʻana a me kaʻike manaʻo. A, i kēia mauʻike manaʻo mea i kaupalena 'ia hoʻi mea hoʻoheheʻeʻia kō i loko o ke kīʻaha o ke kī a me ka hydrolysis konohiki, a pinepine ke kumu o ka haawi hanalima kaʻina hana, akā, i ka luna' like me ka hana ana o ke aloha mea me ka noho ana meaola. Ma nā hua'ōlelo, ke kemika - ka 'epekema o ke ola i loko o olelo o ka loa' iaʻike manaʻo a puni mākou. Kemika ke hai aku nā mea a pau e pili ana i nāʻakika, kumu, paʻakai, a alkalis. Ma kekahi o ka mea hope, e e kūkākūkā hou - paʻakai kalepona. E ka nana aku ma na mea a pau e pili ana i ka paʻakai kalepona mai ka Nine Inch haʻilula, a pau i ka pono ma ka hana a me ke ola.

Penei, paʻakai kalepona, kona haʻilula ua palapala ia penei: Na2CO3, - o ka paʻakai o ka carbonicʻakika, i ua i kapaʻia ka paʻakai paakai o carbonicʻakika, a soda lehu. Kēia mea ikeia me he mea keʻokeʻo pauka haku o ka lole mānoanoa, aʻaʻohe ala a me kaʻawaʻawa loaʻaiʻana i lawa. Ua hiki i loa kaʻapu kōheoheo a me ulcers o ka gastrointestinal'āpana, ina e haule iho lakou iloko o ka kanaka kino i loko o nui mea. Ke mall haʻilula Ua like penei: elua i kekahi paʻa o nā electrons o ka paʻakai'Ātoma palapala hoopaa i ka oxygen ma nā'ātoma (no paʻakai'Ātoma i kekahi oxygen), oxygen ma nā'ātoma pili e hookahi paa ana i ka kalapona'Ātoma, a me ka kalapona, i loko o ka hookahi huli, pili i ka (hui mau) eha electrons i ka ka oxygen'Ātoma. Pela, ke ike i ke kēia mau hana hoihoi kiʻi paʻakai nā'ātoma lilo maikaʻi Ion o kekahi kauoha, oxygen ma nā'ātoma a me ka hopena maikaʻi malama o -2, a me ka kalapona, i hoʻouna aku ai iāʻehā huina'ine i ke kauoha o +4. Penei, paʻakai kalepona, a aho, kona lātoma i polarity ma kekahi mau wahi.

No hoi, aia no he iki okoa paʻakai: paʻakai hydrogencarbonate, NaHCO3 me ka Nine Inch haʻilula, a hiki no hoi i kaʻapu kōheoheo inā loaʻa i loko o ke kino. Paʻakai hydrogen kalepona reacts me ka oi hana ma mua o paʻakai, i eliiaʻi, kahi paʻakai vosstanavlyavaetsya. ʻO kēia ka paʻakai hiki ke reacted me ka mekala 'åkilikai metala o ka oi hana, a, e hoʻihoʻi aku paʻakai. Inā, nae, o ka hydrolysis o ka paakai, ka mea e e kaulana ia paʻakai hydroxide - he ikaika mekala 'åkilikai, a me carbonicʻakika meaʻano nawaliwali ma ke ano maoli, no laila, kuhikuhi, e haawi aku i ka waihona ipu, a me ka lūmaua e'ākilikai' ia, eʻike i kekahi ke hoʻohana i ka phenol-phthalein (i hookohu aku i kākoʻo pāʻoihana ka paʻakai ulaula).

Olelo ana e pili ana i ka paʻakai kalepona, ka Nine Inch waiwai o ka i mai ole oko mai o ka Nine Inch waiwai o ka hydrogen, ka mea, i ke kaulana ia ina ka mahele heheʻe i ka, a, e lawe mai electrolysis o ka paakai pāʻoihana, i ka "hana" ia e e loa'ālike. E ka nana aku.

Electrolysis o ka paʻakai kalepona heheʻe hopena i ua kahiāuli kalepona ion a me nā iole o ka paʻakai. Inā, nae, o ka hydrolysis o ka paakai pāʻoihana, ka mea e 'ai pono i loko o ke kiʻi: ka hydrogen loaʻa hou ma ka anode, ke cathode - hydroxy pae i loko o ka hopena huli mai i koe kalepona anion a me nā iole o ka paʻakai.

Ua mea no hoi e hiki a me ka mea pono e kaulana ia paʻakai kalepona reacts me ka waiwai e like me ka ʻakika ikaika, e laʻa me, nitric, hydrochloric paha sulfuric. Ua Ua hookomoia,ʻo ia hoʻi, ola carbonicʻakika, i laila decomposed i loko o ka wai, a me ka i carbon dioxide a i carbon dioxide, a me ka loaa paakai o kaʻakika, a i huiia i ka paʻakai kalepona.

Kahi o ka mea ia kiʻi ua loaa ia ma ka ohui i ka wailana (aʻaʻohe'ē aʻe, ai ole i ka naoh e e hele!) Ka paakai mea he ikaikaʻakika, akā, i ka naoh huahana mai e loaaʻi ka kinoea, sediment wai paha.
