Cov khoom siv tshuaj
Silver ua tsis yog react nrog dilute hydrochloric acid thiab dilute sulfuric acid tab sis nws reacts nrog kub concentrated sulfuric acid thiab qhov no tshuaj tiv thaiv muab sulfur dioxide dej thiab nyiaj sulfate. Silver reacts nrog ob leeg dilute thiab concentrated nitric kua qaub ua form nyiaj nitrate
Tsis tas li ntawd, magnesium hlau puas yuav ua rau dilute sulfuric acid?
Yog lawm, magnesium yuav ract nrog dilute sulfuric acid ,vim magnesium tuaj yeem oxidized rau Mg (2+) cations thiab ua ke nrog ion sulfate, SO4 (2-) los tsim magnesium sulfate, MgSO4. Qhov no yog kev hloov chaw tshuaj tiv thaiv , qhov twg magnesium hlau displaces hydrogen nyob rau hauv lub molecule ntawm sulfuric acid thiab tawm li H2 gas.
Ib yam li ntawd, yuav ua li cas thaum hlau reacts nrog dilute acid? Thaum a hlau reacts nrog dilute acid , ntsev yog tsim. Lub sijhawm no tshuaj tiv thaiv hydrogen gas yog evolved. Hauv lwm lo lus, thaum a hlau yog ntxiv rau dilute cov kua qaub , ntsev thiab hydrogen gas yog tsim. Sulfate ntsev thiab chloride ntsev yog tsim thaum hlau react nrog dilute sulfuric kua qaub thiab hydrochloric kua qaub.
Tsis tas li ntawd, dab tsi hlau tsis hnov mob nrog dilute sulfuric acid?
Zinc displaces tooj liab hlau , uas ua raws li ib tug catalyst. (tooj liab, nyiaj, kub thiab platinum) yuav tsis hnov mob nrog dilute acid . Lawv ua tsis tau tshem tawm hydrogen los ntawm cov tsis- hlau anion.
Dab tsi yog cov tshuaj tiv thaiv ntawm cov xim dub ntawm cov nyiaj nrog dilute sulfuric acid?
Silver react nrog sulfuric acid tsim tawm nyiaj sulfate, sulfur dioxide thiab dej.

Yuav mg react nrog dilute sulfuric acid?
Magnesium hlau yaj yooj yim hauv dilute sulfuric acid los tsim cov kev daws teeb meem uas muaj cov dej hauv dej Mg (II) ion ua ke nrog hydrogen gas, H2. Kev sib raug zoo nrog lwm cov kua qaub xws li hydrochloric acid kuj muab cov dej hauv Mg (II) ion
Cov hlau nplaum puas yuav lo rau galvanized hlau?
"Galvanized" tsuas yog txhais tau hais tias muaj cov zinc txheej sab nraud ntawm cov Hlau. Yog hais tias cov hlau ismagnetic pib nrog, ces nws tseem yuav sib nqus tom qab galvanizing. Txij li feem ntau tsis muaj laj thawj rau galvanizestainless hlau, cov lus teb yuav luag ib txwm "yog, galvanized steel yog sib nqus"
Cov roj twg yog hloov zuj zus thaum hlau sulfide kho nrog dilute sulfuric acid?
Thaum hlau sulfide reacts nrog diluted sulfuric acid, hydrogen sulfide yog tsim uas yog sau nyob rau hauv lub hub gas los ntawm upward tsiv ntawm huab cua
Yuav ua li cas tshwm sim thaum dilute sulfuric acid yog nchuav rau ntawm zinc phaj?
Thaum dilute Sulfuric acid yog nchuav rau ntawm ib lub zincplate, Zinc Sulphate yog tsim nrog Hydrogen gas.Peb tuaj yeem kuaj cov roj hydrogen los ntawm kev noj cov khoom siv hluav taws xob ze ze, thiab cov roj yuav ignite nrog lub suab nrov
Yuav ua li cas tshwm sim thaum dilute sulfuric acid ntxiv rau hlau sulfide?
A. Thaum twg ?dilute sulfuric acid ntxiv rau kev sib xyaw ntawm cov hlau txhaws thiab cov hmoov sulfur, cov tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau filings uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid los tsim ferrous sulphate thiab tso tawm hydrogendisulphide gas
