Āhuatanga matū waikawa

Waikawa i huaina pūhui matatini tito o ngota hauwai he te kaha ki te kia whakakapia e ngota whakarewa, me he toenga waikawa.

Waikawa he electrolytes. E tāutuhia e ratou hanganga āhuatanga matū waikawa.

Whakarōpū waikawa i runga i ngā whenua:

1. E ai ki te maha o ngā ngota hauwai.

2. Na te aroaro o te hāora.

3. E ai ki te tohu o te dissociation.

E ai ki te maha o ngā ngota hāora (tei tenei i runga i te waikawa āhuatanga matū) e wehea ratou ki anoxic (hauwai sulfide, waikawa pūmāota me te pera i runga i. D.) Na te hāora-kei roto (hauota, sulfurous, me silicic t. D.)

E ai ki te maha o ngā ngota hauwai o te waikawa e:

- monobasic, kei roto i tetahi ngota hauwai (waikawa pūmāota, waikawa hauota);

- dibasic kei ngota e rua hauwai (waikawa pungatara, hauwai pūngāwhā);

- tribasic kei roto e toru ngota hauwai (phosphoric).

Ka rite ki te wehewehea āhuatanga tuatoru o te waikawa ki electrolytes ngoikore (phosphoric, carbonic, etc D.) A electrolytes kaha (pūmāota, hauota, pūngāwhā).

āhuatanga matū waikawa

Ko te aroaro o ngā katote hauwai i roto i rongoā waikawa whakatau ratou taiao waikawa me te reka kawa. Heoi, e kore e taea e koe te tamata ratou i runga i te arero rite taea weranga matū.

taui tohu waikawa tohu ārani mewaro me tona kara i raro i te mana o te waikawa.

tauhohe Waikawa rongoā ki waikura taketake, hua i roto i te hanganga o te tote, me te wai.

tauhohe nga waikawa ki te whakarewa ki te maui o te huānga hauwai i roto i konganuku haupae ngaohiko. Ko te hua ko te tote whakarewa me te hauwai.

tauhohe te waikawa ki te turanga. hua te tauhohenga te tote, me te wai. huaina te tauhohenga i waenga i te waikawa me te alkali (turanga) te tauhohenga neutralization.

tauhohe nga waikawa ki te rongoā tote, ka tukua te huru o te tupu, me te akoranga o te tauhohenga ki te mutunga o te utu katote, i.e. he hohenga he hau ranei te.

Ko te āhuatanga matū o ngā waikawa waro i to ratou ake āhuatanga.

Āhuatanga o te waikawa phosphoric

waikawa phosphoric me ona wairewa waiwai he waikawa nui kahakore pērā i hauota, me te pūngāwhā. Tenei waikawa, i roto i nei te hanganga i reira e toru ngota hāora. He dissociation -hiko o te waikawa phosphoric e wahi stepwise. waikawa Angamaheni - waikawa phosphoric, kua tautuhi ona āhuatanga matū hanganga.

Ko te otinga o te waikawa phosphoric, he hakari i roto i te matua katote Phosphate dihydrogen. Katote e hanga e i roto i te wā dissociation tuarua ko tino iti, me katote Phosphate, te hua o te toru o nga atamira ionization, tata ngaro. I te wā waikawa phosphoric tuatahi - waikawa kaha reo. Mai i reira e toru ngā momo o ngā toenga waikawa i roto i te pāhekoheko o te waikawa phosphoric ki te tai alkali e hanga e whai ake nei: phosphates, phosphates hauwai me phosphates dihydrogen.

kia taiea waikawa Orthophosphoric i ia atu i te waikawa ähua ki pākawa hiriwa, i roto i nei i hanga te he hohenga kōwhai. Ētahi atu waikawa ūkuikui pāhekoheko ki pākawa hiriwa ki te hanga i te hohenga ma. waikawa Orthophosphoric i runga i whakawera me hanga piri wai waikawa pyrophosphoric.

āhuatanga matū o te waikawa pūhaumāota

waikawa pūhaumāota Ko te waikawa monobasic kaha ki te āhuatanga waikawa angamaheni. Taekore paku horekau he otinga wai o te hauwai pūhaumāota i roto i te wai. E huaina tai o te waikawa pūhaumāota "pūhaumāota".

kia kia rite te waikawa pūmāota i te tauhohe i rongoā o te konutai pūhaumāota me te waikawa pungatara, me te hauwai pūhaumāota rewa i roto i te wai. tauhohe waikawa pūhaumāota ki te turanga, reira hanga he tote, me te wai. Na roto i te tauhohe i ki te neutralization alkali puta tauhohenga. Ka taea e koe te manatoko i tēnei tohu. ona huringa tae, whakaaro he otinga kūpapa.

Ko te tauhohenga o te waikawa pūhaumāota me te pākawa hiriwa arata'i ki te hanganga o tai rewakore - pūhaumāota hiriwa e tīwharawhara.

tauhohe waikawa pūmāota ki konganuku hohe. Ki te hoatu ki roto ki te otinga, konutea, tīmata hanganga kaha, me te tuku o te hauwai.

waikawa pūhaumāota Ko te waikawa angamaheni, tauhohe ki turanga, konganuku me tai.
