When Zn metal is kept in CuSO4 solution Cu is precipitated and ZnSO4 is formed because?
When zinc (Zn) metal is placed in a copper sulfate (CuSO4) solution, a displacement reaction occurs because zinc is more reactive than copper. As a result, zinc displaces copper from the copper sulfate solution, leading to the formation of zinc sulfate (ZnSO4) and the precipitation of copper (Cu) metal. This reaction demonstrates the principle of reactivity series in metals, where more reactive metals can displace less reactive metals from their compounds.
What order of active are H Cu Mg Zn?
H, Mg, Zn, Cu
Which one will corrode first of Zn and Cu metals were welded together?
Zinc will corrode first when welded to copper, as zinc is more reactive than copper. This can lead to galvanic corrosion, where the zinc sacrificially corrodes to protect the copper.
Will Ag react with ZnCO3?
Ag (silver) is less reactive than Zn (zinc), so silver will not react with zinc carbonate (ZnCO3). In a chemical reaction, the more reactive element (zinc) will typically displace the less reactive element (silver) in a compound.
What is the product of Zn CUBr2?
Zn + CuBr2 = Cu + ZnBr2
Would a metal in group 13 be more or less reactive than a metal in group 12?
Zn is more reactive than Ga, Cd is more reactive than In; but Tl is more reactive than Hg.
Why is Mg more reactive than Zn?
Mg is more reactive than Zn because Mg has a lower electronegativity than Zn, meaning it is more likely to lose electrons in a reaction. Additionally, Mg has a smaller atomic radius, allowing it to react more readily due to stronger electron-nucleus interactions.
Which metal is more active than Ni and less active than zn?
Copper (Cu) is more active than nickel (Ni) and less active than zinc (Zn).
What is the reaction of ZnSO4 and Cu?
CuSO4+Zn results in Cu+ZnSO4, but the reaction doesn`t take place the other way around CuSO4+Zn results in Cu+ZnSO4, but the reaction doesn`t take place the other way around CuSO4+Zn results in Cu+ZnSO4, but the reaction doesn`t take place the other way around
What happens when Zn strip is dipped in CuSO4 solution?
When a Zn strip is dipped in CuSO4 solution, a displacement reaction occurs where zinc displaces copper from the solution. This results in zinc sulfate being formed and copper metal being deposited on the zinc strip. This demonstrates that zinc is more reactive than copper in this reaction.
Which terminal of the tap water is positive Zn or Cu?
The Cu terminal of tap water is positive, meaning that Zn would be negative. This is because in tap water, copper tends to oxidize more readily than zinc.
What is the molecular total ionic and net ionic for CuNO32 and Zn?
The molecular equation for Cu(NO3)2 and Zn is Cu(NO3)2 + Zn -> Zn(NO3)2 + Cu. The total ionic equation is Cu^2+ + 2NO3- + Zn -> Zn^2+ + 2NO3- + Cu. The net ionic equation is Cu^2+ + Zn -> Zn^2+ + Cu.
What order of active are H Cu Mg Zn?
H, Mg, Zn, Cu
Why does ag not reaplace zn form znso4 solution?
Ag does not replace Zn in a ZnSO4 solution because Ag is lower in the reactivity series compared to Zn. In a single replacement reaction, a more reactive metal will replace a less reactive metal in a compound. Since Ag is less reactive than Zn, it cannot displace Zn in the solution.
Which one will corrode first of Zn and Cu metals were welded together?
Zinc will corrode first when welded to copper, as zinc is more reactive than copper. This can lead to galvanic corrosion, where the zinc sacrificially corrodes to protect the copper.
What are half - reactions of redox reaction CuCl and Zn which gives ZnCl2 and Cu as products?
Zn(s) --> Zn2+(aq) + 2e : Oxidation Cu+(aq) + 1e --> Cu(s) : Reduction
Which metal Zn or Cu can be oxidized easily?
Zinc (Zn) can be oxidized more easily compared to copper (Cu) because zinc has a lower standard reduction potential. This means that zinc is more likely to lose electrons and be oxidized in a redox reaction.
