Kev kuaj rau carbonate ions

Cov npuas raug muab tawm thaum ib qho kua qaub , feem ntau yog dilute hydrochloric kua qaub , yog ntxiv rau xeem kev sib xyaw. Cov npuas yog tshwm sim los ntawm carbon dioxide. Limewater yog siv kom paub meej tias cov pa roj carbon dioxide. Nws hloov smilky / huab thaum carbon dioxide yog npuas los ntawm nws.

Kuj tseem paub yog, vim li cas carbonates hnov mob nrog acids?

Cov tshuaj tiv thaiv acids Zoo li txhua yam hlau carbonates , calcium carbonatereacts nrog acidic kev daws teeb meem los tsim cov pa roj carbon dioxide. Nws yog qhov no tshuaj tiv thaiv uas yog lub luag haujlwm rau limestone fizzingwhen dilute hydrochloric kua qaub muab tso rau ntawm nws qhov chaw.

Tsis tas li ntawd, hom tshuaj tiv thaiv dab tsi yog hydrochloric acid thiab calcium carbonate? Thaum twg hydrochloricacid reacts nrog tej carbonates /hydrogen carbonates Cov khoom tsim yog hlau chloride, dej thiab carbon dioxide. Vim HCl decomposes ntsev ntawm qaug zog. kua qaub . Qhov no tshuaj tiv thaiv tseem hu ua doubledecomposition tshuaj tiv thaiv.

Ib yam li ntawd, nws tau nug, qhov kev sim rau carbonates yog dab tsi?

Kev ntsuam xyuas rau carbonate ions Ib qho kua qaub, xws li dilute hydrochloric acid, yog ntxiv rau xeem compound. Cov pa roj carbon dioxide ua npuas yog carbonate ions muaj nyob. Limewater yog siv los xyuas kom meej tias cov pa roj carbon dioxide. Nws hloov los ntawm ntshiab mus rau mis nyuj thaum cov pa roj carbon dioxide yog npuas los ntawm.

Vim li cas peb ntxiv nitric acid ua ntej nyiaj nitrate?

Yog koj pib ntawm ib qho khoom, nws yuav tsum firstbe yaj nyob rau hauv dej ntshiab. Txoj kev daws teeb meem yog acidified los ntawm ntxiv dilute nitric acid . (Nco ntsoov: silvernitrate + dilute nitric acid .) Cov nitric acid reacts nrog, thiab tshem tawm, lwm yam ions uas kuj yuav ua rau tsis meej pem precipitate nrog nyiaj nitrate.
