Unyango lwamanzi amdakaihlala ibandakanya ukususwa kwezinyithi ezinzima kunye / okanye iikhawuntari ze-organic ukusuka kumanzi amdaka. Ukulawula i-PH ngokongezwa kweekhemidi ze-Acid / Alkaline yinxalenye ebalulekileyo yayo nayiphi na inkqubo yonyango lwamanzi amdaka, njengoko ivumela inkunkuma echithiweyo emanzini ngexesha lenkqubo yonyango.
Amanzi anee-hydrogen ze-hydrogen kwaye ihlawulwe kakubi i-hydroxide ion. Kwi-acidic (PH <7) Amanzi, ugxininiso oluphezulu lwe-hydrogen ye-hydrogen ekhoyo, ngelixa kumanzi angathathi hlangothi, ukugxila kwe-hydrogen kunye nee-ions ze-hydroxide zilungelelene. I-Alkaline (PH> 7) Amanzi aqukethe ngaphezulu kwe-hydroxide engalunganga.
PI-H UMZEKELISOUnyango lwamanzi amdaka
Ngokuhlengahlengisa ngamachiza i-PH, sinokususa izinyithi ezinzima kunye nezinye izinyithi ezinetyhefu emanzini. Uninzi lwabalekayo okanye amanzi amdaka, izinyithi kunye nezinye izinto zokungcolisa ziyanyibilika kwaye azizinzi. Ukuba siphakamisa i-PH, okanye isixa se-hydroxide engeyiyo, ii-ion zentsimbi ezibiweyo ziya kwenza iibhondi nge-hydroxide ehlawulelwayo. Oku kudala ityhefu yentsimbi, engafunekiyo enokuthi isuswe kumanzi amdaka ngexesha elinikiweyo okanye ichithwe kusetyenziswa uxinzelelo lokucoca.
I-PH kunye nonyango lwe-PH yamanzi
Kwimeko ye-acidic ye-ACIDIC, i-hydrogen efanelekileyo kunye nee-ions zentsimbi azinalo naluphi na umququ, bhabha emanzini, aziyi kuchama. Kwi-Houtral PH, i-hydrogen i-hydrogen idibanisa i-hydroxide ion ukwenza amanzi, ngelixa i-ion yentsimbi ihlala ingaguqukanga. EAlkaline ph, i-hydroxide egqithisileyo idibanisa ii-ion zensimbi ukuze izenzele i-hydroxide yentsimbi, enokususwa ngokutyibilika okanye i-piciation.
Kutheni ulawula iPP kumanzi amdaka?
Ukongeza kolu nyango lungentla, i-PH yamanzi inokusetyenziselwa ukubulala iintsholongwane kumanzi amdaka. Uninzi lwezinto eziphilayo kunye neentsholongwane esiqheleneyo kwaye zinxibelelana nayo yonke imihla zilungele imeko yehlangothi okanye kancinci i-alkaline. Kwi-acidic pH, i-hydrogen ye-hydrogen iqala ukwenza iibhondi ezineeseli kwaye ziqhekeze, zinciphise ukukhula kwazo okanye ukuzibulala ngokupheleleyo. Emva komjikelo wonyango lwamanzi amdaka, i-PH kufuneka ibuyiselwe ekungathathi cala ngokusebenzisa iichemicals ezongezelelweyo, kungenjalo ziya kuqhubeka nokonakalisa nayiphi na iiseli eziphilayo ezichukumisayo.
