Take two conical flasks. Label them as I and II. Take a small amount of copper sulphate solution in the first conical flask. Take a small amount of granulated zinc in the second conical flask. Allow the copper sulphate solution to react with the zinc.
i) Name the type of reaction.
ii) Say whether the metal zinc is more reactive or less reactive.
iii) Write the complete and balanced reaction.
iv) Say whether this change is reversible or irreversible.
(i) This reaction comes under the category of displacement reactions.
(ii) A metal is said to be more reactive if it is able to displace another metal from its compound or salt solution. Here, Zinc had displaced Cu from the compound of Copper Sulphate. Hence, Zinc is more reactive.
(iii) The complete and balanced reaction equation is : -
Zn(s) + CuSO4(aq) → Cu(s) + ZnSO4 (aq)
(iv) This change is irreversible as we would not be able to reverse the reaction to get back the reactants from the products under similar conditions.
