Acids react with metals to produce salt and hydrogen gas. For example: 2HCl+Zn→ZnCl2+H2↑\text{2HCl} + \text{Zn} \rightarrow \text{ZnCl}_2 + \text{H}_2 \uparrow2HCl+Zn→ZnCl2+H2↑ Acids
Strong acids completely dissociate in water, releasing all hydrogen ions. Examples include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄). Weak acids partially dissociate, releasing fewer hydrogen ions, like
