Zoo Siab
Kev sib xyaw tshuaj ntawm qee cov cations nrog qee qhov anions pib ua dab tsi hauv chemistry hu ua koj tawm mus. Nyob rau hauv qhov muaj ntau ntsev yaj hauv hiav txwv los yog nag lossis daus, tsim cov zaub mov nruab nrab lossis qib siab. Feem ntau cov no yog cov ntsev ntsev, uas yog, tsim los ntawm inorganic ntsiab.
Nws tau kwv yees tias ib litre dej hiav txwv muaj qhov nruab nrab ntawm 33 txog 39 grams ntsev. Ntau cov ntsev muaj qhov tseem ceeb siv hauv tsev, lwm qhov tseem ceeb rau kev lag luam lossis kev tsim kho.
Cov ntsev feem ntau muaj a crystalline ult infrastructure, txawm hais tias nyob hauv cov xov xwm ua kua lawv yog yaj thiab ionized. Ntsev yog qhov tseem ceeb rau kev muaj sia nyob, lawv pab tswj cov cell homeostasis thiab osmotic tshuav nyiaj li cas rau nws lub peev xwm los nqus dej molecules.
Txawm li cas los xij, cov ntsev ntau dhau tuaj yeem ua rau muaj teeb meem kev noj qab haus huv loj, xws li arterial hypertension. Qee yam muaj sia xav tau cov ntsev ntxhia los tsim txheej txheem tiv thaiv sab nrauv, zoo li lub plhaub thiab lub plhaub. Thiab nws yuav tsum raug coj mus rau hauv tus account tias cov pob txha ntawm txhua lub vertebrates yog ua los ntawm cov ntsev.
Cov ntsev tau los ntawm qhov twg?
Nyob rau hauv qhov ntau ntau ntsev yog concentrated nyob rau hauv cov ntsev flats, qhov no yog hauv cov pas dej nto uas nws cov av tau tsim los ntawm cov ntsev. Raws li cov dej evaporates los ntawm kev ua ntawm lub hnub, cov ntsev sib sau ua ke.
Lawv muaj npe nrov hauv Asmeskas, piv txwv li, salar de Uyuni hauv Bolivia lossis qhov ntawd Atacama hauv Chile. Ib yam nkaus, muaj hiav txwv endorheic lossis pas dej uas muaj ntsev ntau heev: qhov piv txwv paub zoo tshaj plaws yog Hiavtxwv Tuag, nyob ntawm 416.5 meters hauv qab hiav txwv, tshwj xeeb tshaj yog nplua nuj hauv calcium, magnesium, potassium thiab bromine ntsev. Cov ntsiab lus ntsev ntawm Hiav Txwv Tuag nyob ib puag ncig 28%.
Organic ntsev yog cov qhov tshwm sim ntawm cov tshuaj tiv thaiv ntawm alkali, Dab tsi sodium los yog potassium hydroxide, thiab qee qhov muaj roj tsawg. Cov txheej txheem no yog hu ua saponification.Cov ntsev ntsev feem ntau muaj cov khoom siv xab npum, yog li lawv feem ntau yog lub hauv paus rau ntau yam khoom tu.
Piv txwv ntawm ntsev
| Sodium taurocholate | Benzalkonium chloride hmoov |
| Calcium carbonate | Calcium oxalate hmoov |
| Cov tshuaj potassium bromide | Sodium bicarbonate hmoov |
| Magnesium sulphate hmoov | Disodium EDTA |
| Sodium tshuaj dawb | Magnesium carbonate |
| Sodium hypochlorite | Tooj sulphate |
| Tricalcium phosphate | Cov poov tshuaj citrate |
| Ammonium chloride | Ammonium sulfate |
| Cov tshuaj sodium alkyl sulfate | Sodium tellurite hmoov |
| Sodium alkylbenzenesulfonate | Cov poov tshuaj permanganate |
Nws tuaj yeem pab koj:
- Cov ntxhia ntsev
- Oxisales ntsev
- Cov kua qaub
- Ntsev nruab nrab
