Assertion: Zinc can easily displace Copper on reacting with a solution of copper sulphate.
Reason: Copper is a more reactive metal as compared to Zinc.
Explanation:
To understand this assertion and reason, let's first discuss the concept of reactivity series. The reactivity series is a list of metals arranged in order of their decreasing reactivity. The most reactive metals are placed at the top, while the least reactive metals are placed at the bottom.
The reactivity series is as follows:
Potassium
Sodium
Calcium
Magnesium
Aluminum
Zinc
Iron
Lead
Hydrogen
Copper
Silver
Gold
According to the reactivity series, Zinc is placed above Copper. This means that Zinc is more reactive than Copper. When a more reactive metal comes into contact with the compound of a less reactive metal, it can displace the less reactive metal from its compound.
In the given scenario, Zinc is more reactive than Copper. When Zinc metal is added to a solution of copper sulphate (CuSO4), a displacement reaction occurs. The Zinc atoms displace the Copper atoms from the copper sulphate solution, resulting in the formation of Zinc sulphate (ZnSO4) and Copper metal (Cu). This reaction can be represented as:
Zn + CuSO4 -> ZnSO4 + Cu
Therefore, the assertion that Zinc can easily displace Copper on reacting with a solution of copper sulphate is true.
Now let's evaluate the reason given: Copper is a more reactive metal as compared to Zinc.
This reason is incorrect. As per the reactivity series, Zinc is more reactive than Copper. Copper is placed below Zinc in the reactivity series, indicating that it is less reactive than Zinc. Therefore, the reason given is false.
In conclusion, the assertion is true but the reason is false. Hence, option (c) is the correct answer.
