Metals generally react with dilute acids to produce a salt and hydrogen gas. The reaction rate varies depending on the reactivity of the metal. More reactive metals react more vigorously. The general equation for the reaction is:
- Metal + Dilute Acid → Salt + Hydrogen Gas
Examples:
- Zinc (Zn) reacts with dilute hydrochloric acid (HCl) to produce zinc chloride (ZnCl2) and hydrogen gas (H2).
- Magnesium (Mg) reacts with dilute sulfuric acid (H2SO4) to produce magnesium sulfate (MgSO4) and hydrogen gas (H2).
The hydrogen gas produced is flammable and can be ignited. The rate of reaction is influenced by factors such as the concentration of the acid and the surface area of the metal.
