What happens:
* Acid (typically containing hydrogen ions, H+) reacts with a base (typically containing hydroxide ions, OH-) to form salt and water.
* The hydrogen ions from the acid combine with the hydroxide ions from the base to form water (H2O).
* The remaining ions from the acid and base combine to form a salt.
General equation:
Acid + Base → Salt + Water
Example:
* Hydrochloric acid (HCl) + Sodium hydroxide (NaOH) → Sodium chloride (NaCl) + Water (H2O)
Key points:
* Neutralization is an exothermic reaction, meaning it releases heat.
* The pH of the solution changes. Acidic solutions have a pH less than 7, while basic solutions have a pH greater than 7. Neutralization brings the pH closer to 7.
* The strength of the acid and base determines the extent of the reaction. Stronger acids and bases react more vigorously.
Applications:
Neutralization reactions have numerous applications, including:
* Controlling acidity in industrial processes
* Digestion in our bodies (stomach acid is neutralized by bicarbonate ions)
* Producing salts (many salts are produced by neutralization reactions)
* Making antacids (to neutralize excess stomach acid)
