Hauv qhov tshuaj tiv thaiv no, hydrogen atom ntawm nitric acid hloov los ntawm zinc. Nws yog vim reactivity los yog electrochemical series. Lub peev xwm oxidation ntawm zinc yog siab dua li ntawm hydrogen. Yog li, lub xeev oxidation ntawm zinc hloov ntawm 0 mus rau +2.
Yuav ua li cas thaum zinc hnov mob nrog dilute nitric acid?
Zinc reacts nrog concentrated Nitric acid rau tsim Zinc nitrate, nitrogen dioxide thiab dej.
Cov khoom tsim dab tsi thaum zinc reacts nrog dilute nitric acid?
Cov khoom tsim thaum zinc reacts nrog dil. Nitric acid yog zinc nitrate & hydrogen gas.
Thaum Zn reacts nrog dilute nitric acid nitrous oxide tsim?
Teb: Zinc reacts nrog dilute nitric acid ua N2O raws li qhov sib npaug hauv qab no. 4Zn + 10HNO3=4Zn(NO3)2 +N2O+5H2O.
Cov tshuaj tiv thaiv ntawm zinc thiab nitric acid yog dab tsi?
Zinc nitrate feem ntau yog npaj los ntawm kev ua kom cov zinc nyob hauv nitric acid, cov tshuaj tiv thaiv no yog concentration nyob ntawm seb, nrog cov tshuaj tiv thaiv hauv cov kua qaub tseem ceeb kuj tsim ammonium nitrate: Zn + 2 HNO 3 (diluted) → Zn(NO3)2 + H2O.
