Why is it not possible to maintain the concentration of ZnCl₂ solution when it comes into contact with aluminum?

1. ZnCl₂ solution cannot be maintained in contact with aluminum.
2. Aluminum has greater reactivity compared to zinc.
3. Because of its high reduction potential.
4. The solution's concentration will be lost.

Correct answer: Aluminum has greater reactivity compared to zinc.

Solution

Al is more reactive than Zn because it has a lower reduction potential, meaning it can displace Zn from its solution. This makes option B correct.
