Hydrogen gas is not liberated when the following metal is added to dil. HCl

Options

  1. AAg
  2. BZn
  3. CMg
  4. DSn

Correct answer

A. Ag

Step-by-step solution

The order of reactivity of given elements is Ag < H < Zn < Sn < Mg As, Ag is less reactive than hydrogen, it cannot replace hydrogen from HCl and H ₂ gas is not liberated.
