Thaum twg barium chloride reacts nrog poov tshuaj sulfate , barium sulfate thiab poov tshuaj chloride arc ua. Qhov sib npaug sib npaug rau cov tshuaj tiv thaiv no yog: BaCl_2(aq) + K_2SO_4(aq) rightarrow BaSO_4(s) + 2KCl(aq) Yog tias 2 moles ntawm poov tshuaj sulfate react, Cov tshuaj tiv thaiv noj moles ntawm barium chloride.
Tsis tas li ntawd, puas yog k2so4 tsim cov dej nag?
Ib qho kev daws ntawm barium chloride yog tov nrog ib tug daws ntawm poov tshuaj sulfate thiab a precipitate daim ntawv . Los ntawm kev tshuaj xyuas cov cai solubility peb pom tias, thaum feem ntau sulfates yog soluble, barium sulfate yog tsis yog. Vim nws yog insoluble hauv dej peb paub tias nws yog tus nag xob nag cua.
Tom qab ntawd, lo lus nug yog, hom precipitate yog baso4? Barium sulfate yog hlau sulfate nrog formula BaO4S. Zoo insoluble nyob rau hauv dej nyob rau hauv chav tsev kub, nws yog feem ntau siv raws li ib tug tivthaiv nyob rau hauv cov roj zoo drilling kua nws tshwm sim raws li cov ntxhia barite. Nws muaj lub luag haujlwm raws li qhov nruab nrab radioopaque. Nws yog barium ntsev thiab hlau sulfate.
Qhov thib ob, BaCl2 h2so4 puas tsim cov dej nag?
Nws yog nag lossis daus tshwm sim raws li barium ion txuas rau sulfate ion rau daim ntawv barium sulphate uas nag xob nag cua tawm ntawm cov tshuaj thaum cov hydrogen ua ke nrog chlorine rau daim ntawv hydrochloric acid.
Dab tsi yog cov khoom ntawm ob qhov kev hloov pauv ntawm barium chloride thiab potassium carbonate?
Potassium carbonate thiab barium chloride : Potassium carbonate thiab barium chloride yog ob qho tib si soluble ntsev uas yuav teb hauv a ob chav tshem tawm cov tshuaj tiv thaiv los tsim cov soluble poov tshuaj chloride thiab insoluble barium carbonate . Qhov no yuav precipitate tawm ntawm kev daws.
Pom zoo:
Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Puas yog kev sib xyaw potassium chloride nrog sodium nitrate muaj tshuaj tiv thaiv?
Tsis yog nws tsis yog vim tias ob qho tib si potassium chloride thiab sodium nitrate tsim cov tshuaj aqueous, uas txhais tau hais tias lawv yog soluble. Lawv yaj hauv dej kom tiav, uas txhais tau hais tias tsis muaj cov tshuaj tiv thaiv pom hauv cov khoom. Thaum peb sib xyaw KCl nrog NaNO3, peb tau KNo3 + NaCl. Qhov sib npaug ionic rau qhov sib tov yog
Yuav ua li cas thaum barium chloride reacts nrog poov tshuaj sulfate?
Thaum barium chloride reacts nrog potassium sulfate, barium sulfate thiab potassium chloride arc tsim. Qhov sib npaug sib npaug rau cov tshuaj tiv thaiv no yog: BaCl_2(aq) + K_2SO_4(aq) rightarrow BaSO_4(s) + 2KCl(aq) Yog tias 2 moles ntawm poov tshuaj sulfate react, Cov tshuaj tiv thaiv noj moles ntawm barium chloride
Yuav ua li cas tshwm sim thaum aqueous tov ntawm sodium sulphate thiab barium chloride sib tov?
Thaum cov tshuaj aqueous ntawm sodium sulphate reacts nrog ib tug aqueous tov ntawm barium chloride, precipitate ntawm barium sulphate yog tsim thiab tom qab cov tshuaj tiv thaiv tshwm sim. ii. Yog hais tias cov reactants nyob rau hauv lub cev muaj zog, ces cov tshuaj tiv thaiv yuav tsis tshwm sim. Nws yog ib qho kev hloov pauv ob npaug nrog rau nag lossis daus
Dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm aqueous lead II nitrate nrog aqueous sodium bromide?
Cov tshuaj tiv thaiv ntawm aqueous sodium bromide thiab aqueous lead (II) nitrate yog sawv cev los ntawm qhov sib npaug net ionic equation. 2Br−(aq)+Pb2+(aq) →PbBr2(s) 2 B r − (a q) + P b 2 + (a q) → P b B r 2 (s)
