How do metals react with acids?

Answer 1

Most metals react with acids to produce a corresponding salt and hydrogen gas.

Shown here is the reaction between zinc and hydrochloric acid to produce zinc chloride and hydrogen.

Zn + 2HCl --> ZnCl2 + H2

Nitric acid reacts with some less reactive metals, Here copper reacts with nitric acid to produce copper II nitrate, water, and nitrogen dioxide.

Cu + 4 HNO3 --> Cu(NO3)2 + 2NO2 + 2H2O

Answer 2

Many metals react with acid to liberate hydrogen, and form metal ions. The metal is oxidised.

Answer 3

metals do not react with dillute acids to displace hydrogen.

Answer 4

Acid + Reactive Metal --> Salt + Hydrogen Gas

Answer 5

• The outcome of chemical reaction of metals with acid salt and hydrogen.

• For example: Cu(s) + 2HCl(aq) → CuCl2(aq) + H2(g)
