a. Thaum twg? dilute sulfuric acid ntxiv mus rau ib tug sib tov ntawm hlau filling thiab sulfur hmoov, tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau Cov ntaub ntawv uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid tsim ferrous sulphate thiab tso tawm hydrogendisulphide roj.

Kuj tseem paub yog, yuav ua li cas thaum hlau sulphide reacts nrog sulfuric acid?

Thaum twg hlau sulfide yog ntxiv rau dilute sulfuric acid , koj yuav tau hlau sulfate, dej thiab sulfur dioxide raws li cov khoom.

Kuj Paub, cov roj twg yog hloov zuj zus thaum hlau sulfide kho nrog dilute sulfuric acid? hydrogen sulfide gas

Qhov thib ob, yuav ua li cas thaum hlau ntxiv rau dilute sulfuric acid?

Cov tshuaj tiv thaiv ntawm hlau nrog acids Hlau hlau dissolves nkag rau hauv dilute sulfuric acid Thaum tsis muaj oxygen los tsim cov kev daws teeb meem uas muaj cov dej Fe (II) ion ua ke nrog hydrogen gas, H2. Yog tias muaj cov pa oxygen, qee qhov Fe (II) oxidizes rau Fe (III).

Yuav ua li cas tshwm sim thaum sib tov ntawm hlau thiab sulfur yog rhuab?

Thaum twg hlau thiab sulfur yog cua sov ib qho tshuaj tiv thaiv yuav tshwm sim I.e. Sulfur ua ke nrog cov hlau hauv sib tov nyob rau hauv lub xub ntiag ntawm kub ua form Hlau sulfide (FeS).
