2. Reaction with metals: Many acids react with certain metals to produce hydrogen gas. For instance, hydrochloric acid (HCl) reacts with zinc to produce zinc chloride and hydrogen gas.
3. Color change: Acids can change the color of certain plant pigments. The ripening of fruits and vegetables can be caused by the formation or destruction of excess acids.
