KCET2008ChemistryHydrogen
Hydrogen gas is not liberated when the following metal is added to dil HCl
Options
- AAg
- BZn
- CMg
- DSn
Correct answer
A. Ag
Step-by-step solution
The metals, present below hydrogen in the electrochemical series, cannot liberate hydrogen from the dilute acids. Among the given metals only Ag is present below hydrogen in electrochemical series, so it does not evolve hydrogen with dil HCl. Ag + dil HCl No reaction
