Ngokuvamile kuyadingeka ukwazi ukuthi i-asidi yenhlabathi yokutshala izimbali ezithile noma izitshalo zemifino. Yingxenye ye-lime emhlabathini futhi ibizwa nangokuthi ibhalansi ye-acid-base. Kumele kube kuhle kakhulu izitshalo ukuthi zithole zonke izakhi kahle, kanti isivuno sasiwufanele futhi sivame. Ukukhishwa kwe-asidi kunezinhlobo ezinhlanu eziyinhloko: kusuka enhlabathini enamandla kakhulu (3-4 pH) kuya ku-alkali eqinile (8-9 pH). Ukungathathi hlangothi, futhi, kubhekwa inhlabathi nge-acidity ka-6-7 pH.
Indlela yokulinganisa i-acidity yenhlabathi?
Ukuze unqume ukuthi iyiphi inhlabathi kusayithi lakho, zama enye yezindlela ezilandelayo:
- ukusebenzisa idivayisi ekhethekile yokulinganisa i-acidity yenhlabathi - ibizwa ngokuthi i-acid meter;
- uma kusayithi lonyaka odlule akuzange likhule lutho, khona-ke unake izitshalo ezihleliwe kuleli zwe. Inhlabathi encane enomsoco noma engathathi hlangothi ivame ukuhlala i-clover, inambuzane , i-bondweed, umama nomama. Futhi ngokuqinile kakhulu, i-floores, i-horsetail, i-plantain, i-buttercup ikhula;
- Kuzosiza ukunquma i-acidity yenhlabathi, ngokungavamile, iviniga evamile. Ukuze wenze lokhu, hamba amaconsi ambalwa alolu ketshezi endaweni encane yomhlaba ubone ukuthi kwenzekani. Uma kukhona uhlamvu olunezibhamu, njengalapho i-quenching soda - lokhu kuyisibonakaliso sokuthi inhlabathi ayihambisani nendawo noma isondelene ne-alkaline. Uma kungekho zibonakaliso ezinjalo, i-acidity yenhlabathi iphezulu. Ukuyibuyisela esimweni esijwayelekile, kuzodingeka ukwengeze ufulawa lwamakhwala, u-choki noma u-dolomite enhlabathini enjalo;
- uhlola i-currant emnyama. Thatha amaqabunga ambalwa esiqhingini salesi sitshalo bese ugcwalisa ngamanzi abilayo. Uma amanzi epholile, hlanganisa amaqabunga nge-spoon bese ubhala ngobumnene umhlabathi elincane egumbini, i-acidity ofuna ukuyilinganisela. Umphumela kufanele wahlulelwe umbala wamanzi: uzophenduka obomvu (lokhu kusho ukuthi inhlabathi iyasebenza kakhulu), pink (medium-acid), eluhlaza (ukungathathi hlangothi) noma umthunzi obuluhlaza (alkaline).
Umthamo Wokumisa Umhlabathi
Idivaysi elula yokuthola i-acidity yenhlabathi ingakwazi
Okuyinhloko yale ndlela kubandakanya ukulungiselela izikweletu ze-litmus. Lokhu kwenziwa kanjalo. Gweba ikhanda iklabishi ebomvu (violet) futhi ulungiselele i-decoction kuyo, lapho kudingeka khona ukugoqa iphepha lephrinta okwesikhashana. Ngemuva kokuba imicu isomile, ungaqala ukukala i-pH yenhlabathi. Mane nje uhambise isampula yasemhlabathini bese uyifinyelela emgqeni kanye nomdwebo wephepha lenkomba, ukuze kuthole kahle. Umbala lapho iphepha lenziwe khona, futhi kuzokutshela mayelana ne-acidity yenhlabathi. Umbala obomvu wephepha unquma ukuba khona kwe-asidi, futhi luhlaza futhi luhlaza okwesibhakabhaka.
