Zamkati
Kuphatikiza kwamankhwala ena am'madzi enaake ndi anions ena kumachokera mu umagwirira wotchedwa chemistry inu pitani kunja. M'chilengedwe pali zambiri mchere umasungunuka m'nyanja kapena mwaphokoso, Kupanga mchere wapakatikati kapena wapamwamba kwambiri. Mwambiri izi ndi mchere wamchere, ndiye kuti, wopangidwa ndi zinthu zachilengedwe.
Akuyerekeza kuti lita imodzi yamadzi am'nyanja imakhala ndi magalamu a 33 mpaka 39 amchere. Mchere wambiri ndi wofunikira ntchito zapakhomo, zina ndizofunikira pakampani kapena zomangamanga.
Mchere nthawi zambiri amakhala ndi makina opangira ma crystalline, ngakhale atolankhani amadzimadzi ali kusungunuka ndi ionized. Mchere ndi wofunikira kwa zamoyo, amathandizira sungani cell homeostasis ndi osmotic balance chifukwa chokhoza kutsatsa mamolekyulu amadzi.
Komabe, mchere wambiri ukhoza kubweretsa mavuto azaumoyo, monga matenda oopsa. Zamoyo zina zimafunikira mchere wamchere kuti apange zoteteza kunja, ngati zipolopolo ndi zipolopolo. Ndipo ziyenera kukumbukiridwa kuti mafupa a zinyama zonse amapangidwa ndi mchere.
Kodi mcherewo umachokera kuti?
M'chilengedwe mchere wambiri zimakhazikika m'malo okhala mchere, ili mkati nyanja zapamwamba zomwe zimakhala ndi mchere. Pamene madzi amasanduka nthunzi chifukwa cha zochita za dzuŵa, mcherewo umadziunjikira.
Iwo ndi otchuka ku America, mwachitsanzo, salar de Uyuni ku Bolivia kapena ku Atacama ku Chile. Mofananamo, pali nyanja kapena nyanja zomwe zili ndi mchere wambiri: chitsanzo chodziwika kwambiri ndi cha Nyanja YakufaIli pamtunda wa mamita 416.5 pansi pa nyanja, makamaka calcium, magnesium, potaziyamu ndi bromine salt. Mchere wa Nyanja Yakufa uli pafupifupi 28%.
Mchere wamchere ndi Zotsatira za zomwe zimachitika pakati pa alkali, Chani sodium kapena potaziyamu hydroxide, ndi ena mafuta acid. Izi zimadziwika kuti saponification.Mchere wamchere nthawi zambiri amakhala ndi zotsukira, chifukwa chake nthawi zambiri zimakhala maziko azinthu zingapo zoyeretsera.
Zitsanzo zamchere
| Sodium taurocholate | Benzalkonium mankhwala enaake. |
| Calcium carbonate | Calcium oxalate |
| Bromidi wa potaziyamu | Sodium bicarbonate |
| Mankhwala enaake a sulphate | Kusokonezeka kwa EDTA |
| Sodium mankhwala enaake | Mankhwala enaake a carbonate |
| Sodium hypochlorite | Sulphate yamkuwa |
| Tricalcium mankwala | Potaziyamu citrate |
| Ammonium mankhwala enaake | Sulphate ya ammonium |
| Sodium alkyl sulphate | Sodium tellurite |
| Sodium alkylbenzenesulfonate | Potaziyamu permanganate |
Itha kukutumikirani:
- Mchere wamchere
- Mchere wa oxisales
- Mchere wamchere
- Mchere wosalowerera ndale
