Question

Name a metal that reacts vigorously with dil.HCl

Answer 1

• Metals react with dilute acids to form metal salts and hydrogen gas.
• Alkali metals can react vigorously with dilute HCl to give hydrogen and metal salt.
• An example of such a metal is sodium.

$\underset{\mathrm{Sodium}}{2\mathrm{Na}\left(\mathrm{s}\right)}+\underset{\mathrm{dil}.\mathrm{Hydrochloric}\mathrm{acid}}{2\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{chloride}}{2\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
