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.
