Zinc reacts with both acid and base to give hydrogen gas.
Zn + 2NaOH Na2ZnO2 + H. Zinc react with sodium hydroxide to produce zincate sodium and hydrogen. This reaction takes place at a temperature near 550°C.
The reaction between zinc and hydrochloric acid is Zn + HCl = H2 + ZnCl2. It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. Zinc reacts quickly with the acid to form bubbles of hydrogen.
