What causes passivity of specific metals in conc. nitric acid?

WebHydrogen gas is not evolved when a metal reacts with dilute nitric acid because nitric acid is a strong oxidizing agent. So, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidizes this hydrogen to water. WebSep 19, 2014 · the metal is dissolved; In order to form hydrogen, protons need to be reduced to hydrogen atoms which then combine to $\ce{H2}$. $$\ce{2 H+ + 2 e- -> H2}$$ The metal serves as an electron donor and is oxidized, e.g. $$\ce{Zn -> Zn^{2+} + 2 e- }$$ The more noble a metal is, the more reluctant it is to lose electrons. truly mediaWebSep 9, 2024 · Sep 3, 2024. #2.

"Web2 years ago. Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently.

WebCu will react in a similar way producing Cu2+. 3Cu + 8 HNO3 (dilute) → 3Cu (NO3)2 + 2NO + 4H2O. Remember, remember of H2 by reaction of a metal and HNO3 is rare because H2 will be easily oxidized to h2o by the powerful oxidizing agent, HNO3. The exact reasons behind the reactions actually lie with electrochemistry. WebApr 2, 2024 · $$\ce{Pb + 4 HNO3 → Pb(NO3)2 + 2 NO2 + 2 H2O}$$ Since the solvent is concentrated nitric acid (in which lead(II) nitrate has very low solubility) and the resulting solution contains nitrate ions, anhydrous crystals of lead(II) nitrate spontaneously form as a result of the common ion effect.
