Question

How do acids react with metals?

Answer 1

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.

`Mg + 2HCl -> MgCl_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 `Mg^+2` and `Cl^-1` forming `MgCl_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.

I hope this was helpful.
