Question

What is the limitation of the given reaction:
Zn(s) + 2HCL(aq) -> ZnCL2 (aq) + H2 (gas)​

Answer 1

Answer:

ZnCl2 is not a very commonly used metal, which makes 'adding it to a more reactive metal' useless. Thus this reaction has a limitation.

Hope this helps . . . also comment if further doubt.
