What Occurs When Metals Come Into Contact With Acids
Acids are corrosive liquids. However, when it reacts with some objects or metal, it produces some gas.
Most metals react with acids, but not all. Nevertheless, not all metals react in the same way to acids.
When an acid reacts with metal, salt and hydrogen gas are produced.
The general equation that describes the chemical reaction between an acid and metal is: metal + acid = salt + hydrogen gas.
Example
Zinc powder reacts with hydrochloric acid, which releases gas and zinc chloride.
Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
These reactions are exothermic reactions. The reaction rate depends on the metal used and how high up it is in the reactivity series.
Hydrogen can be tested in such chemical reactions by the squeaky pop sound it produces when burnt after the metal acid reaction with the help of a candle or any other fire source.
