n ib chemical tshuaj tiv thaiv nruab nrab ntawm ob lub tebchaw nyob rau hauv uas qhov chaw ntawm txhua qhov sib hloov los ua ob lub tebchaw tshiab (AB + CD = AD + CB) Synonyms: ob chav decomposition , Hom metathesis: ob npaug hloov tshuaj tiv thaiv.

Ib yam li ntawd, muaj pes tsawg hom kev cuam tshuam ob npaug ntawm kev puas tsuaj?

Muaj peb hom kev hloov pauv ob zaug : nag lossis daus, neutralization thiab gas tsim. Peb yuav tham txog txhua tus thiab mus dhau ib qho piv txwv rau txhua tus.

Tsis tas li ntawd, puas yog ob chav decomposition thiab ob chav hloov chaw zoo ib yam? Qhov txawv ntawm kev hloov pauv ob npaug thiab ob chav decomposition cov tshuaj tiv thaiv yog tias cov kev hloov pauv ob npaug Cov tshuaj tiv thaiv yog tshuaj lom neeg cov tshuaj tiv thaiv nyob rau hauv uas cov khoom ntawm ob reactants pauv nrog ib leeg whereas lub ob chav decomposition cov tshuaj tiv thaiv yog ib daim ntawv ntawm kev hloov pauv ob npaug cov tshuaj tiv thaiv nyob rau hauv uas ib los yog ntau tshaj

Piv txwv li, ob chav decomposition yog dab tsi?

A ob chav decomposition Cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv uas cov ions zoo thiab tsis zoo ions hauv ob lub tebchaw hloov cov koom tes los tsim ob lub tebchaw tshiab. Ntau ob chav decomposition cov tshuaj tiv thaiv yog nag lossis daus. AgNO3(aq)+NaCl(aq) →AgCl(s)+NaNO3(aq) Lwm yam yog acid-base neutralization reactions.

Ib qho piv txwv ntawm kev hloov pauv ob zaug yog dab tsi?

A ob npaug - hloov cov tshuaj tiv thaiv tshwm sim thaum qhov chaw ntawm ob lub tebchaw ionic pauv, ua ob lub tebchaw tshiab. Ib tug yam ntxwv ntawm a ob npaug - hloov Qhov sib npaug yog tias muaj ob lub tebchaw ua reactants thiab ob lub tebchaw sib txawv raws li cov khoom. Ib piv txwv yog. CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)
