Muchinyorwa chakapfuura, takakurukura kuti mamwe machira ekare anogona kubvaruka nyore nyore mumiti yekuwachira nekuda kwekusakwana kwepH kwenguva refu. Saka, tingaziva sei kukosha kwepH yejira rakagezwa? Nhasi, tichagovana nemi dzimwe mhinduro dzakajairika.
Kuti pH yejira rakagezwa yakakodzera here kana kuti kwete chimwe chezviratidzo zvemhando yekugezwa. China ine mitemo ine chekuita ne pH yejira rakagezwa revanhu vose.
Mukushanda kuri kuitwa pari zvino kwezvirimwa zvekuwachira mbatya, kune nzira nhatu dzekutarisa kana pH yakakosha.
Nzira Yekupedzisira Yekuongorora Mvura Yekushambidza (Nzira Isina Kunanga)
Mafekitori ekuwachira mbatya anoda acid inobvisa tsvina kuti agadzirise pH yemachira uye abvise sipo nemasaririra anodhaka ari mujira.
● Nzira isina kunanga inoshandisa mvura yekupedzisira yekugeza kuti ione huwandu hwepH yayo kuitira kuti ione kukosha kwepH yerineni.
Nzira iyi iri nyore uye inodhura zvishoma. Inogona kushandiswa panzvimbo yacho mumafekitori ekuwachira mbatya uye inoshanda zvakanyanya pabasa rekushanda. Zvisinei, mhedzisiro yacho inosiyana nekuti chinhu chekuongorora hachisi jira pacharo.
Nzira yekuedza titration yeAcid-Alkali Test Solution yeLinen (Direct Method)
● Donhedza mushonga wekuyedza acid-base pajira rakagezwa → cherechedza ruvara rwaro → enzanisa ruvara neColorimetric plate → fungidzira kukosha kwepH
Nzira iyi yakananga ine nguva pfupi yekuyedza uye inodhura zvishoma. Inogona kuitwa mumafekitori ekuwachira mbatya uye ine mashandisirwo akasimba. Inoda kuti vanoshanda vazivenzira yekuwacha mbatyauye hukama huripo pakati pekuchinja kweruvara rwemushonga uye pH. Mhedzisiro yekuedza ine hukama hwakanyanya nehukobvu hwemachira, zvasara zvemvura, huwandu hwemushonga wekuyedza, uye ruzivo rwevashandisi. Vanhu vakasiyana vanogona kuva nekududzira kwakasiyana kwemhedzisiro imwe chete. Kunyangwe mhedzisiro yekuedza ingave yakasiyana zvishoma, kururama kwayo kwakanyanya kupfuura kwenzira isina kunanga.
Nzira Yekuongorora pH yeChikamu Chemvura Chemachira
Nzira iyi inofanira kupedzwa nesangano rekuongorora hutachiona.
● Tora sampuli yemachira → Shandisa chishandiso chekuyedza → Edza pH yemvura inotorwa kubva mujira
Nzira iyi inosanganisira tsvakiridzo yakadzama pazvinhu zvese, saka mhedzisiro yekuyedza yakarurama uye yakagadzikana. Iyi nzira yakatarwa yekupa mishumo yekuyedza nerabhoritari yebato rechitatu inovimbika uye ine humbowo.
Mhedziso
Nzira idzi nhatu dzese dzine zvadzinobatsira. Nzira yakananga neisina kunanga dzinoshanda pakuongororwa kwezuva nezuva nekuti dzinokurumidza uye dziri nyore. Mvura inotorwa kubva munzira yekuyedza machira inofanira kuitwa nenyanzvi yekuongorora machira. Nekubatanidza nzira nhatu idzi,zvirimwa zvekuwachira mbatyainogona kudzora pH yerineni.
