Asidi Carbonic: onse mudziwe

asidi Carbonic (H2CO3 chilinganizo) - ofooka diacid. Pamene njira mkangano ndi linakwiriridwa mu mpweya woipa komanso madzi. Asidiyu n'kofunika kwambiri osati nyama, komanso zomera. Anthu, H2CO3, ndi mchere ake ali m'gulu la machitidwe gawo lotetezedwa magazi. Mothandizidwa ndi machitidwe gawo lotetezedwa kukhala bwino asidi-zamchere mu thupi, amene ndi koyenera kuti kugwira ntchito bwinobwino. The dissociation zidulo mu zotsatira amadzimadzi sing'anga mu mapangidwe anions ndi cations. The ion ndende n'kofunika kuti otaya njira zambiri amuzolengedwa mu thupi la nyama ndi zomera. Mu matenda ena, ndi yogwira zimene magazi ndi ankatembenukira kwa chidulo (mmatumbo chilonda ndi m'mimba) kapena zamchere (ndi sepsis, chibayo) mbali. Ngati acidosis kumawonjezera ion wa hydrogen ndende. asinthire, nayenso imautsa chitukuko cha chikomokere, imene pamapeto pake zotsatira imfa ya nyama. Pamene alkalosis m'magazi kumaonjezera ndende ya cations, chifukwa mu kafumbata ndi imfa ya boma nyama.

asidi Carbonic inakhazikitsidwa m'zaka zimene CO2 ndi H2O. Akatswiri ambiri amakhulupirira kuti kukula yaikulu kwambiri zomera dziko wosazindikira amagwirizana ndi ndende kwambiri mpweya woipa mu mlengalenga. Kukula kwambiri ambiri unkachitika zomera amene anali wamkulu ndi mkulu (5-10%) ndende asidi carbonic mu mlengalenga.

Tikumbukenso kuti zomera zigwirizana theka la mpweya. asidi Carbonic wakudya mbewu, motero kumathandiza kuti solubility zigawo zikuluzikulu mchere nthaka. Choncho, mu nkhani iyi, ndi zofunika chigawo chimodzi cha nthaka. Chifukwa asidi carbonic kumabwezera mmbuyo nitrifying tizilombo, nthaka ayenera kukhala ndi ndende osachepera zace.

Choncho, kupeza mkulu zokolola zofunika kukwaniritsa ndende ya anati acid. The ofufuza za kafukufuku wawo awo anapeza kuti pamene kutumikiridwa tsiku m'nthaka carbonic asidi (400 cm3) ndi mpweya (1200 cm3), amabala kawiri monga zomera ambiri poyerekeza ndi zomwe inalibe mankhwala awa.

m'mudzi amakhala ndi kuchuluka kwa mpweya nthaka, kotero njira ya nitrification ndipo inali kuwola ndi kwambiri. Anapeza kuti masamba m'nkhalango kwathunthu kuwola ndinso mkati mwa chaka. Chotero nitrification wolimba amapezeka steppes lapansi. Mu ndondomeko ya kuwonongeka kwa zinthu organic anamasulidwa ndi yambiri asidi carbonic. Yotsirizira theka nthawi yolemera kuposa mpweya, asidi carbonic likulowerera chozama mu nthaka kuposa mpweya, ndipo ali zotsatira zopindulitsa pa zigawo mchere.

Ndi chakuya akulima zatsalira organic kugwera mu zigawo zakuya za nthaka, kumene kulibe O2, koma pali unyinji wa asidi carbonic. Mu nkhani iyi, nitrification akuchedwa kwambiri. M'mikhalidwe izi kuwola ndinso mchere zigawo ndi mankhwala asafe sumangoyambika. chunks yaikulu zaka manyowa kugona mu nthaka, osati peregnivaya. Nzika amakakamizidwa kugula feteleza kupanga (kainite, superphosphate, Chile nitrate). Nzeru tillage kusintha chomera zokolola. Ichi ndi chifukwa makamaka chakuti mu ndondomeko ya ntchito m'dziko zigawo chapamwamba nthaka zatsalira organic kukhala. Kuti akonze zinthu mulingo woyenera chitukuko ndi kubalana tizilombo nitrifying.

Phosphorus, amene ali nthaka, osati nthawi zonse chosakanikirana ndi zomera. Tribasic kashiamu wa phosphate - sungunuka mankhwala. Choncho, nthaka wolemera mankhwala phosphoric asidi, ndi wotembenuka mu osabereka.
