Hydrogen gas is not liberated when the following metal is added to dil. HCl
- A Ag
- B \(\mathrm{Zn}\)
- C \(\mathrm{Mg}\)
- D \(\mathrm{Sn}\)
Answer & Solution
Correct Answer
(A) Ag
Step-by-step Solution
Detailed explanation
The order of reactivity of given elements is \(\mathrm{Ag} < \mathrm{H} < \mathrm{Zn} < \mathrm{Sn} < \mathrm{Mg}\) As, Ag is less reactive than hydrogen, it cannot replace hydrogen from \(\mathrm{HCl}\) and \(\mathrm{H}_{2}\) gas is not liberated.
