Zn + 2HCl → ZnCl2 + H2
In this reaction, zinc atoms lose two electrons each to become Zn2+ ions, while hydrogen ions from HCl gain one electron each to become H2 gas. The reaction can be described as an oxidation-reduction reaction, where zinc is oxidized (loses electrons) and hydrogen is reduced (gains electrons).
The reaction between HCl and Zn is typically observed as a bubbling or fizzing reaction, as hydrogen gas is produced. The rate of the reaction can be affected by several factors, such as the concentration of the acid, the surface area of the zinc, and the temperature.
