Thaum ob qhov kev daws teeb meem aqueous react, lawv qee zaum tsim cov khib nyiab hauv cov tshuaj. Cov khoom yog hu ua precipitate. Cov nag xob nag cua tshwm sim thaum cov cations ntawm ib qho reactant thiab cov anions ntawm ib tug thib ob reactant pom nyob rau hauv aqueous tov ua ke los ua ib tug insoluble ionic khoom uas peb hu ua precipitate.

Yuav ua li cas koj thiaj paub yog nag lossis daus?

Yog tias tus nqi ntawm cov khoom lag luam ion ntau dua li tus nqi ntawm Ksp , ces cov dej nag yuav tsim. Kev tsim ntawm cov precipitate txo qis cov concentration ntawm txhua ions kom txog thaum cov khoom ion yog sib npaug zos rau Ksp, thaum twg nag los nag.

nag xob nag cua tsim nyob qhov twg?

Kev tsim ntawm ib qho chaw tsis sib haum xeeb yuav qee zaum tshwm sim thaum cov tshuaj uas muaj cov cation tshwj xeeb (ib qho txiaj ntsig zoo ion) yog tov nrog lwm cov tshuaj uas muaj ib qho anion (ib qho tsis zoo ion). Cov khoom sib cais hu ua nag xob nag cua.

Dab tsi ua rau nag los tsim?

Cov khoom hu ua precipitate. Cov dej nag tshwm sim tshwm sim thaum cov cations ntawm ib qho reactant thiab cov anions ntawm ib tug thib ob reactant pom nyob rau hauv aqueous tov ua ke los ua ib tug insoluble ionic khoom uas peb hu ua precipitate. … Ib daim ntawv precipitate yog cov khoom ntawm cov tshuaj tiv thaiv ntawm cov ions yog insoluble hauv dej

nag xob nag cua piv txwv?

Silver nitrate thiab potassium chloride yog cov tshuaj tiv thaiv nag lossis daus vim cov khoom siv nyiaj chloride yog tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv tuaj yeem pom los ntawm nag lossis daus vim tias 2 ionic kua daws tau hnov mob rau ib daim ntawv khoom.
