Question

Dog what happens when a metal reacts with an acid ?,​

Answer 1

Most metals react with acids in a single replacement reaction in which the metal replaces the hydrogen ions in the acid.

Mg + 2 HCl ➡️H2 + MgCl2

A few metals that don't do this are the coinage metals (Cu, Ag, Au). These metals tend to only react with concentrated nitric acid in an oxidation-reduction reaction where the metal gets oxidized and some of the nitrate gets reduced to nitrogen dioxide.

Cu + 4 HNO3 ➡️ Cu(NO3)2 + 2 NO2 + 2 H2O

This reaction would be a bit different for Ag going to Ag+ ion or Au going to the Au3+ ion.
