Question

I Can copper sulphate solution be stored in a zinc container? Give suitable reason for your
answer
Erns/n = -0.76 V Elett = 0.34 V​

Answer 1

Answer:

Copper is less reactive than zinc. Zinc will replace the copper from its salt solution. ... So copper sulphate solution cannot be stored in a zinc pot.

Explanation:

Answer 2

Answer:Zinc is more reactive than copper. Therefore, zinc can displace copper from its salt solution. If copper sulphate solution is stored in a zinc pot, then zinc will displace copper from the copper sulphate solution. Zn+CuSO 4 ​ ⟶ZnSO 4 ​ +Cu Hence, the copper sulphate solution cannot be stored in a zinc pot.If it is positive, it means cell reaction will occur, and one cannot store the solution in the pot.

Explanation:

If the standard oxidation potential of the metal behaving as pot is greater than the standard oxidation otential of the metal consisting of solution ,then Ec−.cell will be positive and one cannot store the solution in the pot. ∴Ec−.cell=(Ec−.reduction)cathode−(Ec−.reduction)anode =Ec−.Cu2+∣Cu)−Ec−.Zn2+∣Zn =0.34−(−0.76)=1.10V
