Zimene CaCl2, H2SO4

Chimodzi mwa zokhumudwitsa mayendedwe loyamba kuphunzira malamulo mankhwala ndi maziko ndi kulemba zochita ndi mankhwala. Choncho, mafunso okhudza zimene zimachitika kwa CaCl2, H2SO4 sadapezamo nthawi ndi mwadongosolo. Tiyeni tione waukulu "vuto" mphindi.

Lembani maselo aone kuti pali

Zimachitika pakati mankhwala enaake kashiamu (mchere) ndi asidi sulfuric umayenda mwa limagwirira kuwombola.

Zizindikilo zotani awa:

• kugwirizana awiri pa polowera (zopangira);
• kugwirizana awiri pa linanena bungwe (mankhwala);
• wathunthu kusowa zinthu zophweka.

Kusinthana ndi aliyense magulu ena zotakasika, ndi reactants ndi kusinthidwa, ndi aone kuti pali amatenga mawonekedwe:

CaCl2 + H2SO4 = CaSO4 + 2HCl.

Monga mmene taonera, zovuta awiri mankhwala, kusintha ayoni kupanga mankhwala osiyana kwambiri: a mchere watsopano (CaSO4) ndi hydrochloric acid (HCl).

Kuyenda mpaka mapeto

Kuyankha funso limeneli zimangochitika polemba kalata CaCl2, H2SO4 anachita aone kuti pali mu mawonekedwe maselo. Mtundu wa mankhwala ndi chifuniro chonse zimadalira. Mpaka kumapeto kwa ndondomekoyi ndi pa nkhani ya maphunziro:

• sungunuka kanthu (sludge);
• oyaka pawiri (mpweya);
• malodissotsiiruschego reagent (madzi, ofooka electrolyte).

Mu kuganizira CaCl2, H2SO4 akakhala mwa mankhwala kashiamu sulphate anachita - bwino sungunuka pawiri precipitates monga tebulo.

Choncho, ndondomeko kuwombola udzachitike mpaka kumapeto.

Mwachidule amaayoni mawonekedwe pakati kujambula CaCl2, H2SO4

Kulemba mankhwala onse sungunuka mu ayoni ndi kuchepetsa kumatchula magulu zotakasika timapeza maikwezhoni awiri zosadziwika:

• wathunthu amaayoni mtundu kujambula pakati CaCl2, H2SO4

^{ca 2+ + 2cl - + 2h +} + choncho ₄ ^2- = caso ₄ ⁺ 2h + + 2cl ^-

• ndi chidule cha aone kuti pali ndi

ca ²⁺ + choncho ₄ ^2- = caso _4.

Tiyenera kukumbukira kuti ayoni yekha utoto salt sungunuka, zidulo, zapansi (ichi mosavuta anatsimikiza kwa matebulo wapadera). Ofooka electrolytes mtundu carbonic kapena asidi acetic nthawi zonse zolembedwa mu mawonekedwe maselo.

Tsopano inu mukudziwa momwe zimachitika pakati mankhwala enaake kashiamu (mchere), ndi asidi sulfuric.
