WebCorrect option is D) Metals readily react with acid and produce hydrogen gas which burns with a pop sound. Metals are placed above hydrogen in reactivity series and displace it during a reaction with an acid. As acids have a property of giving H + ions. A resultant is formed with release of hydrogen gas. WebMar 22, 2024 · The acids, hydrochloric or citric, have a common property : they produce $\ce{H+}$ in water. These ions are necessary to react with copper and hydrogen peroxide $\ce{H2O2}$.Indeed metallic copper reacts with hydrogen peroxide $\ce{H2O2}$ and an acid in the following way : $$\ce{Cu + H2O2 + 2 H+ -> Cu^{2+} + 2 H2O}$$ So whatever …
Reaction of acids and bases with metals (video) Khan Academy
WebIn this case, the metal in question has to be reactive enough to reduce the water t. Metals which are more reactive than hydrogen in the reactivity series can react with acid and … WebWhen a metal reacts with water, a metal hydroxide and hydrogen are formed. For example, sodium reacts rapidly with cold water: sodium + water → sodium hydroxide + … downtown east singpost
Reactivity of Hydrogen - Meaning, With Water, Metals …
WebSep 19, 2014 · hydrogen gas is formed; 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. WebGenerally, they don't react, but zinc and aluminum are the exceptions; the ones who don't play by the rules. e.g.: Zn reacts with NaOH to form sodium zincate (Na₂ZnO₂), a salt, and hydrogen. Zn + NaOH ---> Na₂ZnO₂ + H₂ Al reacts with NaOH to form sodium aluminate (NaAlO₂) and hydrogen. Al + NaOH ---> NaAlO₂ + H₂ Hope this helps. :) P. S.: WebUndiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly … cleaners edenbridge
