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
Acids and bases have many daily uses. Acids like citric acid (in lemons), acetic acid (in vinegar), and carbonic acid (in sodas) are common in food. Hydrochloric acid
Acids are substances that release hydrogen ions (H⁺) in aqueous solutions. They have a sour taste, turn blue litmus red, and have a pH less than 7. Common
Indicators are substances that change color to show whether a solution is acidic or basic. Common indicators include litmus (red in acid, blue in base), phenolphthalein (colorless in
