Inowanzodiwa kuti uzive asidi yevhu yekudyara mamwe maruva kana michero yemiriwo. Icho chiyero chemarara mukati mevhu uye chinonziwo acid-base balance. Inofanirwa kuva yakanakisisa yezvirimwa kuti iwane zvose zvinovaka muviri, uye kukohwa kwaiva nehupamhi uye yakawanda. Kubata kwe aciditi kune marudzi mashanu makuru: kubva kune ivhu rakaoma (3-4 pH) kusvika zvakasimba alkali (8-9 pH). Kusarerekera, zvakare, kunoonekwa sevhu ne acidid ya 6-7 pH.
Nzira yekuyera sei acidity yevhu?
Kuti uone kuti ivhu ripi pane nzvimbo yako, edza imwe yenzira dzinotevera:
- kushandiswa kwechigadzirwa chakakosha chekuyera asidi yevhu - inonzi "meter" mamita;
- kana panzvimbo yegore rakapera haina kukura chero chinhu, saka nyatsoteerera kumiti yakagadzirirwa munyika ino. Nzvimbo duku zvishoma kana dzisina kusimba dzinowanzogara muvhaver, nettle , bindweed, amai-uye-nhingikadzi. Uye pane zvakasimba acidic, zvakare, pasi, bhiza, muchero, buttercup kukura;
- Ichinobatsira kuziva kuti asidi yevhu, asinganzwisisiki, iyo inowanzovhiniga. Kuti uite izvi, dya madonhwe mashomanana emvura iyi pane zvishoma zvepasi uye ona zvazvinoitika. Kana pane chimiro chaanoita nemabhuruu, sekuti kana quenching soda - ichi chiratidzo chokuti ivhu haritsigiri kana kuti iri pedyo ne-alkaline. Kana kusina zviratidzo zvakadaro, asi acidity yevhu yakakwirira. Kuti udzose zvakare kune zvakasarudzika, unofanira kuwedzera yerinestone, choko kana ufa we dolomite kune ivhu rakadaro;
- kuedza ne black currant. Tora mashizha mashomanana kubva kumusango wechimiro ichi uye uzadze nemvura inopisa. Apo mvura inoputika, funganisa mashizha nemupuni, uye zvinyoronyoro uchinge huwandu hwevhu mukati megirasi, iyo acidity yaunoda kuikera. Chigumisiro chinofanirwa kutongwa nemuvara wemvura: iyo ichashanduka yakajeka (izvi zvinoreva kuti ivhu rakanyanyisa acidic), pink (medium-asidi), ruvara (rusingatanidzi) kana mumvuri webhuruu (alkaline).

Chimwe chinhu chakanaka chokugadzirisa asidi yevhu inogona
Icho chinonyanya kukosha chemuitiro chinosanganisira kugadzirira litmus zvikwereti. Izvi zvakaitwa saizvozvo. Geda musoro wekundu (violet) kabichi uye gadzira decoction kubva mairi, umo zvakakosha kuvhara pepa rekupiritsa kwenguva pfupi. Mushure mokunge mapepa aoma, unogona kutanga kuyera pH yevhu. Kungosvibisa mhando yevhu uye kuifambisa mubheti pamwe chete nepepeti yemapepa, kuitira kuti iwane yakanaka. Muvara umo pepa yacho yakasvibiswa, uye ichakuudza nezve acidity yevhu. Mutsvuku wepepa inogadza kuvapo kweAsiri, uye ruvara uye bhuruu - alkali.
