How do acids react with metals?

May 7, 2014

An acid metal reaction typically results in a salt and the release of Hydrogen gas.

An example of is would be Magnesium in Hydrochloric Acid.

$M g + 2 H C l \to M g C {l}_{2} + {H}_{2}$

This is a single displacement reaction where the anion from the Acid recombined with the metal to form the salt, in this case $M {g}^{+} 2$ and $C {l}^{-} 1$ forming $M g C {l}_{2}$ and the Hydrogen gas gets released.

Keep in mind that Hydrogen is a diatomic element and will always be ${H}_{2}$ in its gas phase.
