Cov tshuaj tiv thaiv ntawm CaCl2, H2SO4

Ib tug ntawm cov neeg ko taw blocks nyob rau hauv thawj kauj ruam ntawm kev kawm tshuaj cov cai thiab cov me nyuam yaus yog sau tshuaj tshua. Yog li ntawd, cov lus nug txog cov kev sis raug zoo ntawm CaCl2, H2SO4 pom tsis tseg thiab systematically. Cia peb kawm lub ntsiab "teeb meem" moments.

Cov ntaub ntawv molecular kab zauv

Sis ntawm calcium chloride (ntsev) thiab sulfuric acid ntws los ntawm cov kev pauv mechanism.

Hallmarks ntawm no cov tshuaj tiv thaiv yog:

• ob kev sib txuas ntawm cov inlet (raw khoom);
• ob kev sib txuas ntawm cov zis (khoom);
• tiav tsis muaj tej yam yooj yim tshuaj.

Sib nrog txhua lwm yam reactive pawg, lub reactants yog hloov, thiab cov kab zauv yuav siv sij hawm rau hauv daim ntawv:

CaCl2 + H2SO4 = CaSO4 + 2HCl.

Raws li yuav pom, ob tug complex tshuaj, hloov ions tsim ib tug heev txawv tebchaw: ib tug tshiab ntsev (CaSO4) thiab hydrochloric acid (HCl).

Yuav kom ntws mus rau qhov kawg

Teb rau lo lus nug no yuav ua tau tsuas yog sau ntawv mus rau CaCl2, H2SO4 cov tshuaj tiv thaiv kab zauv nyob rau hauv molecular daim ntawv. Lub hom ntawm cov khoom thiab yuav tag nrho nyob ntawm seb. Txog rau thaum xaus ntawm tus txheej txheem yog nyob rau hauv cov ntaub ntawv ntawm kev kawm ntawv:

• soluble teeb meem (sludge);
• volatile compound (gas);
• malodissotsiiruschego reagent (dej, tsis muaj zog ntsha).

Nyob rau hauv kev saib xyuas rau CaCl2, H2SO4 cov ntaub ntawv muaj cov calcium sulfate cov tshuaj tiv thaiv khoom - tsis zoo soluble compound precipitates raws li mus rau lub rooj.

Li ntawd, cov kev pauv txheej txheem yuav tsum muaj nyob rau txog rau thaum xaus.

Sau ua ke ionic daim ntawv ntawm cov ntaubntawv povthawj siv CaCl2, H2SO4

Sau ntawv tawm tag nrho cov soluble sib txuas rau hauv ions thiab txo rov muaj dua reactive pawg, peb tau ob tug sib npaug tus tsis paub:

• tiav ionic daim ntawv cov ntaubntawv povthawj siv ntawm CaCl2, H2SO4

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

• ib tug shortened daim ntawv ntawm cov kab zauv

ca ²⁺ + li ₄ ^2- = caso _4.

Nws yuav tsum tau nco ntsoov hais tias tias tsuas yog ions pleev xim rau soluble ntsev, kua qaub, bases (qhov no yog yooj yim txiav txim los ntawm tshwj xeeb ntxhuav). Tsis muaj zog electrolytes hom carbonic los yog acetic acid yog ib txwm sau nyob rau hauv lub molecular daim ntawv.

Tam sim no koj paub yuav ua li cas lub sib raug zoo ntawm calcium chloride (ntsev), thiab sulfuric acid.
