Yog, nws pom tseeb tias tooj liab yuav tsis hnov mob nrog hydrochloric acid rau qhov yooj yim vim li cas nws qis dua hydrogen hauv cov tshuaj reactivity. Yog li, tooj liab tsis tuaj yeem hloov cov hydrogen hauv HCl los ua CuCl2. Yog li ntawd, thaum tooj liab (Cu) reacts nrog hydrochloric acid (HCl) yuav tsis muaj tshuaj tiv thaiv.
Vim li cas Cu tsis hnov qab HCl?
Tab sis Cu tsis hnov mob HCl vim qhov txo qis ntawm Cu yog siab dua li ntawm hydrogen. Tsuas yog cov hlau uas muaj peev xwm txo qis dua li ntawm hydrogen react nrog cov tsis-oxidising acids. i.e. Li no, cov tshuaj tiv thaiv tsis ua tau.
Yuav ua li cas thaum HCl ntxiv rau tooj liab?
Yuav tsis muaj kev cuam tshuam. Tooj liab yog cov hlau tsis muaj zog heev, thiab nws tsis hnov mob nrog hydrochloric acid. Nws yog saum tooj liab hauv cov hlau reactivity series, yog li tooj liab tsis tuaj yeem hloov cov hydrogen hauv HCl los ua CuCl2.
Yuav ua li cas thaum Cu reacts nrog dil HCl?
Yog tooj liab siab dua, nws yuav hloov hydrogen los ntawm HCl, thiab qhov tshwm sim yuav tshwm sim. … Tooj liab yuav tsis hloov hydrogen nyob rau hauv ib tug compound. Qhov ntawd txhais tau tias tsis muaj qhov tshwm sim ntawm tooj liab thiab dilute hydrochloric acid. Tsis muaj dab tsi yuav tshwm sim thaum cov ntaub ntawv no muab tso ua ke!
Puas acid react with Cu?
Yog li, tooj liab puas ua rau cov kua qaub? Tsis yog, tooj liab tsis hnov mob tsis muaj oxidizing acidzoo li dilute sulfuric acid, hydrochloride, hydrobromide, thiab lwm yam vim tias nws cov peev xwm txo tau siab dua li ntawm hydrogen. Yog li ntawd, tooj liab muaj nyob rau hauv qab hydrogen nyob rau hauv reactivity series ntawm hlau.
