Thaum ib aqueous tov ntawm sodium sulphate reacts nrog ib aqueous daws ntawm barium chloride , nag xob nag cua barium sulfate yog tsim thiab tom qab cov tshuaj tiv thaiv yuav tshwm sim. ii. Yog hais tias cov reactants nyob rau hauv lub cev, ces cov tshuaj tiv thaiv yuav tsis tshwm sim. Nws yog ib qho kev hloov pauv ob npaug nrog rau nag lossis daus.

Yog li, cov khoom dab tsi yog tsim thaum aqueous sodium sulfate thiab aqueous barium chloride sib xyaw ua ke?

Lo lus nug: Sodium sulfate , Na2SO4, and Barium Chloride , BaCl2, Yog Soluble Compounds Daim ntawv Clear Solutions. Txawm li cas los xij, Thaum Aqueous Kev daws ntawm Sodium sulfate Thiab Barium chloride yog sib xyaw ua ke , Ib Dawb Khoom (ib Precipitate) Cov ntawv Raws li pom hauv daim duab hauv qab no.

Kuj Paub, thaum sodium sulphate reacts nrog barium chloride cov tshuaj tom qab cov tshuaj tiv thaiv muaj feem ntau? Thaum 'sodium sulphate tov ' reacts nrog 'barium chloride tov ' cov tshuaj tom qab cov tshuaj tiv thaiv muaj feem ntau yog sodium chloride . Kev piav qhia: Sodium sulphate reacts nrog ' daws ntawm barium chloride ' ua rau muaj kev hloov pauv ob npaug tshuaj tiv thaiv nyob rau hauv uas cov ions pauv.

Ua kom pom qhov no, dab tsi yog nag lossis daus tsim thaum BaCl2 thiab Na2SO4 sib xyaw?

Ib tug dawb nag xob nag cua yog barium sulfate tsim . Ob chav decomposition tshwm sim, thiab dawb nag xob nag cua ntawm barium sulphate yuav yog tsim . BaCl2 + Na2SO4 = BaSO4 + 2 NaCl. BaSO4 yog insoluble hauv dej.

Thaum aqueous barium chloride tov nrog aqueous sodium sulfate ib daim ntawv precipitate sau ib qho kev sib npaug rau qhov kev tshwm sim no?

Dab tsi yog qhov kev sib npaug rau barium chloride reacts nrog kua sodium sulfate tawm mus barium sulfate as a nag xob nag cua thiab thiab daim ntawv ua kua sodium chloride ? Ib txoj kev mus sau yog: BaCl2 + Na2SO4 → BaSO4↓ + 2NaCl.
